An error coin is a coin that was not correctly made during its manufacture or is outside of acceptable tolerance limits. For example, error coins may have problems such as being struck off-center, having the wrong planchet type, having the planchets improperly produced, so they are too thick or too thin, improperly claded, or any number of other problems that occur during coin manufacturing.

Additionally, the coin die may be damaged during production and lead to several error coins being produced from the damaged coin dies. For example, it may crack due to overuse. Conversely, a coin die may not have been made correctly, leading to various coin errors.

Mint errors should not be confused with die varieties, coins that bear differences on their surfaces due to variations in the dies used to strike them, such as how dates and mint marks were punched, features doubled during die creation, etc. The primary determining factor between error coins and die varieties is that die varieties are reproduced hundreds or thousands of times because the imperfection was on the coin die used to produce the coins. However, there is still some debate among numismatists about what constitutes an error coin versus a die variety.

Classification of Error Coins

There are three different classifications of error coins. Some error coins may have a combination of these problems.

1. Planchet: Any problem with the planchet that the coin was made on. This may include incomplete planchets, wrong metal, cracked, chipped, clipped, or thickness.
2. Die: A coin die is a hardened piece of metal that is used to strike the coins in the coining press. Any coin die that is not made in adherence to United States Mint standards. This may include preproduction errors and damage to the coin die during the coining process.
3. Strike: Any problem with the physical production of the coin in the coining press. There is numerous classification of errors that are due to the improper striking of a coin. Examples include off-center strikes, multiple strikes, rotated dies, misaligned dies, weak strikes, overstrikes, etc.

Types of Mint Errors

• Die Cap – Occurs when a planchet is fed into the coining press, the previous planchet did not eject and the first planchet sticks to one of the coin dies. After repeated strikes, the first planchet starts taking the form of a bottle cap.
• Wrong Planchet – The incorrect planchet is fed into the coining press and does not match the dies that are loaded in the press.
• Off-Centers – The planchet is not centered between the two coin dies in the coining press.
• Broadstrikes – The coining collar that holds the coin between the two dyes is not fully engaged in the coin is struck anyway.
• Partial Collars – The coining collar is partially engaged in results in a malformed coin edge.
• Brockages – One coin is struck on top of another coin in the coining chamber.
• Double & Triple Struck – The coin is struck multiple times.
• Die Adjustment – The coin is struck with not enough pressure due to the coin press operator adjusting the machine.
• Bonded Coins – Two coins are struck together.
• Double Denominations – A coin is first struck with one denomination and then fed through a coining press that has coin dies for a different denomination.
• Coins Struck on Feeder Finger Tips – The coin press uses “feeder fingers” to feed the planchets into the coining press. Occasionally, the feeder finger gets struck with the coin design instead of the planchet.
• Struck Fragments – Metal fragments from various sources can end up in the coining press and get struck with the coin design.
• Proof Errors – Any proof coin that was not properly prepared according to proof coin standards.
• Transitional Errors – When the mint changes from one metallic composition to another and a previous planchet with the old composition ends up getting struck as newly dated coins.
• Fold-Over Strikes – A planchet is fed into the coining press in the vertical position and get struck on its edge instead of on its surface.
• Missing Edge Lettering – Coins that are supposed to have lettering on the edge is missing. This is most prevalent on Presidential Dollars.

The Official Price Guide to Mint Errors

Although error coins are very difficult to price and a definitive price guide for coin errors does not exist, Alan Herbert authored The Official Price Guide to Mint Errors. The seventh and last edition was published in 2007 before Herbert died in January 2013. The book does an excellent job of creating a cataloging system for mint errors.

In order to completely understand error coins, you must first understand the minting process. Herbert does an excellent job of presenting the minting process in Chapter 2. He dives deep into the minting process for modern coins as well as classic United States coins. The following chapters detail each and every category of error that can happen. This follows the PDS (Planchet, Die, Strike) system for cataloging the different types of coin errors that can occur.

For each type of coin error, Alan lists relative rarity level, a value between 1 and 8 (1 being very common and 8 being extremely rare), and a value range based upon current market conditions. Unfortunately, this book was produced in 2007 making relative rarity evaluations and coin values obsolete since new examples of error coins can be discovered. Additionally, the coin collector demand for error coins changes over time. Some error coins may be extremely popular one year, and then unpopular the next year. He makes it very clear that the value of an error coin can only be determined when you go to sell it.

Thousands worth of error coins are what collectors are looking for

Thousands worth of error coins are what collectors are looking for

Publication time – 2022.04. ridiculous coinage errors.

Mistakes have been made throughout history in the minting process, from printing the wrong denomination to pressing two different coins.

From a practical point of view, coins with minting errors are worth nothing. However, many collectors like these coins, as they complement the collection with their uniqueness.

Coins with minting errors are usually destroyed by the producers, but in rare cases, a few copies end up in circulation and are in great demand among numismatists.

Most often, the cost of such coins reaches a substantial amount, depending on the rarity and minting error. The price can vary from a few dollars to several hundred thousand. Here are some of the most common error coins:

US Gold Coin

Price: 2500-250,000 USD

Misspelled US gold coins are very rare, with some sellers asking for up to $100,000 or more! The US$10 Quarter Ounce “American Gold Eagle” is the most common mint error gold coin. Manufacturers mistakenly stamped it with an unfinished factory stamp with an unnecessary mint mark – the letter “w”. Collectors consider this error one of the most valuable. Over time, the value of this coin increases rapidly, so its acquisition is guaranteed to bring profit in the future.

Violation or alteration of the metal composition

Cost: 2500-250 000 USD

Such errors occur when coins are minted on a metal blank with incorrect parameters or incorrect metal composition. There are several coins in circulation with this error:

• 1943 Lincoln cents were minted on blanks for 1942 bronze cents. This example is the most famous in the category of this error.
• Instead of cladding, at 1965 American coins were plated with silver.
• Other examples are very rare in circulation. But they exist.

Embossing on Incorrect Billets

Cost: 125-200,000 USD

This embossing error occurs when the wrong denomination of billets are fed into the press. As a result, the stamp imprints the design on a coin of a different size. Despite the fact that these coins are usually found and destroyed by the manufacturers, the copies that have entered circulation are highly valued by collectors.

Center Offset

Cost: 75-125,000 USD

This is one of the most famous mint errors. The offset problem arises from the incorrect positioning of the workpiece in the embossing area. The impact of the press is directed to the edge of the coin, and not to the center. This results in an irregular shape and thickness of the coin.

Shape-shifting error

Cost: 50-75,000 USD

Coins with this error have a higher markup than coins with other errors. An error occurs when a freshly minted coin sticks to the die and stays there long enough to form the shape of a bottle cap when struck. The number of strokes may vary. This error results in coins having varying thicknesses and a faded appearance caused by too many punches.

Double strike

Cost: 200-50 000 USD

This error occurs when the stamp strikes the same coin two or more times. The images overlap and overlap each other. This error also leads to different variations in the shape of the coin. Once in circulation, such coins can cost up to several tens of thousands of dollars!

Bent coins

Cost: 10-30,000 USD

An error occurs when two coin blanks accidentally fall into the same holder. The stamp hits the coins that are on top of each other. The result is a rare type of impression, when a coin of one denomination is minted on a blank intended for a different denomination.

Double coins

Value: 750-20,000 USD

A coin with this mint error is one of the most sought after among collectors. This error occurs when a minted coin receives an extra die stroke intended for another coin. An impression of a different denomination on this type of coin is visible with varying degrees of visibility.

Coins with stamp error

Price: 50-20 000 USD

One of the most unusual inaccuracies in minting coins is stamp error. Producers must ensure that the correct impact force is used when minting coins for the best coin quality. If the die is not properly adjusted, the coin may break on impact, or the impact may not be strong enough to produce.

To determine the correct pressure, manufacturers first prepare a series of test pieces of coins. A test series is usually considered a failure if the hits on the coin are too weak. Mints regularly destroy these coins because they are extremely rare in circulation.

Error caused by coin feeding

Cost: 2,500-15,000 USD

Coins are transferred by machine to a special impact chamber, but sometimes due to a malfunction it jams. Therefore, the impact is on the coin in the coin feeder. The coin in the mechanism, struck by a stamp, has concave, straight and angular imprints. Coins also often break or crumble when this error occurs.

Single Coins

Value: 1500-12,500 USD

This mint error is caused by a feeder mechanism that feeds blanks of coins to the minting press. An error occurs when a minted coin is ejected incorrectly and another coin blank is placed in the top feed mechanism. The force of impact connects the coins.

Incose marriage

Value: 50-12 500 USD

This minting error involves two coins and occurs when an already minted coin gets stuck in the feed mechanism and itself acts as a stamp, imprinting a mirror impression of its own surface on the blank of another coin. Coins with an error from time to time do not pass quality control and go into circulation. Once in the hands of collectors, this type of coin becomes very valuable.

Curved Coin

Cost: 750-10,000 USD

This is one of the hardest mistakes on this list. It occurs when a coin gets stuck between two coin dies. The blows are so powerful that the coin bends. Bent coins come in a variety of shapes and sizes, making each one unique. Their appearance is determined by the strength and number of press strokes.

Inaccurate strike error

Value: 40-10,000 USD

These coins have a wider and flatter appearance than usual. What is causing this error? Most often, due to mechanical defects, the coin falls out of the coin acceptor. When dropped, the coin is in the wrong position, so it is incorrectly and inaccurately struck by the die.

Coin Fragments

Price: 75-5000 USD

Fragments are the small pieces of metal that remain after the minting process. However, for a piece of a coin to be considered a fragment, it must weigh at least 25% of the total weight of the coin.

One-sided coinage

Price: 20-4000 USD

One-sided coins appear when two blanks of coins are placed between the stamps at the same time. As a result, the sides clinging to each other remain without a pattern. Such coins can also have a displaced center if the blanks were of different sizes. Usually this minting error is caused by various mechanical problems.

Conclusion

Coin collecting is alien to some people, because numismatists sometimes equate their hobby with a fever that does not go away until the missing coin is in their hands.

Interested in collecting coins? The first step is to find a reliable supplier, as more primitive mint errors can be counterfeited these days. The safest destination is certified coins. However, in some cases, the coin certification service can cost more than the coin itself.

Collectible and defective coins can also be an interesting investment, especially old coins with minting errors. Mint error coins are becoming less common these days due to advances in technology, and modern defective coins are not valued very highly.

Errors on the coins of the USSR

During the Soviet Union, more coins were issued that had inconsistencies. These specimens are not defective and are valued by knowledgeable collectors. Errors on them were made due to the usual human inattention: the use of the wrong stamp or its incorrect manufacture, equipment failure or malfunction.

Manufacturing date does not match the number of tapes

10 kopecks 1956 with 15 ribbons instead of 16

At that time, the number of ribbons on the coin meant the number of republics that were part of the USSR. On the 3-kopeck coin from 1946, instead of 11 ribbons, sixteen were depicted. And on a coin with a face value of 10 kopecks of the same year – only seven. In the year 48 of the last century, there were only 11 ribbons on a copy of 2 kopecks, and there should already be 16. In 1957, there were even more errors in the number of ribbons. 16 ribbons were minted on 1, 3, 10 kopeck coins, although according to all the rules there should already be 15.

The circular inscription on the coat of arms does not match the year of minting

located in a circle;
3 kopeck coin from 1937 of the last century – there is an inscription on the coat of arms, but it corresponds to the model of 1926-1935;
5-kopeck coin dated 33 of the last century — there is no inscription on the coat of arms in a circle;
15-kopeck coin dated 1935 of the last century – an inscription in a circle on the coat of arms of the sample of 1931;
1-ruble coin from 77 of the last century (the coin is dedicated to the Olympics) – the coat of arms is depicted in the same way as on a copy of 1 ruble from 75 years.

The year of issue does not match the date on the edge of the coin. So, for example, on the edge of a 50-kopeck coin of 1988, 1987 is indicated, and on 1 ruble 1990 years is 1989. But on copies with a face value of 50 kopecks from 1924, a chasing from the royal coin flaunts on the edge.
