To find out if your coin is a double die variety, visit the Wexler Coin and Die Variety Files. Thousands of coins are listed on the website. You can also find the best varieties of commemorative cents, including doubled die coins. The best doubled die varieties are those with very prominent doubling on the UNITED STATES OF AMERICA and ONE CENT.
Most books present the die varieties for the particular series. Other titles present the historical information, the lure of a series, or national archive records. The authors of Wexler’s Coin and Die Varieties have tried to analyze all possible varieties. Their method is not exhaustive, but it certainly helps identify coins with varying die characteristics. They even include descriptions of die varieties and their prices. And the detailed macro photos make identification a breeze.
Mint marks are another common type of variety. The lower part of the date of the 1956-D Lincoln cent displays a stamped S. The attributer at CONECA does not believe that this is a punch, but it is included in the Wexler Files as 1956-D 1C/WDMM-001. The image between the lower 1 and 9 is considered a “diffuse” variety in the Wexler Files.
This is an overview of the various types of dies and coins listed in the Wexler Die Variety File. The “Submitted By” column indicates the person who submitted a coin for attribution. Often, a coin will be attributed to a variety by looking at it side by side with another coin. While a collection of die varieties can cost hundreds of dollars, they are relatively cheap. Most varieties go for a few dollars, so an excellent opportunity to start a collection.
You can find additional information about a coin’s die type by looking at its listing numbers. The listings for Statehood Quarters and Presidential Dollars include the state’s postal abbreviation. For example, 1955-P 25C/MN WDDO-001 signifies the Obverse Die #1 for the 1955-P Minnesota State quarter. Similarly, the listing for a Lincoln Cent RPM is the same as for a 1935-P proof coin.
Doubled die varieties are important for collectors because they are easy to spot. They tend to have nice spreads and significant amounts of doubling. They are nice additions to any doubled die collection. However, sometimes they are overshadowed by another doubled die variety. For example, the 1972 Lincoln cent is listed as Obverse Die #2, but its “major” doubled die variety is the 1982-A, which is the second doubled Lincoln cent.
During the late 1960s, the Mint began to modify the design of the Lincoln cent. This was necessary because of problems with impressions from working dies. It removed the lugs on the hubs of the dies and allowed the design to be pressed deeper into the die. The result was the introduction of doubled dies with strong spreads and a wide spread. These two changes helped the Lincoln cent design become more popular and widespread.
Doubled die coins are also rare. Doubled die coins are rare, and can fetch nice prices on auction sites. Because of their rarity, doubled die coins are more valuable than their “normal” counterparts. However, they are only one type of doubling. If you’re thinking about buying a coin with a doubled die, you should be cautious and make sure that the seller is honest.
This book also covers the Lincoln cents. It is an 8 1/2 by 11-inch format and contains over 750 photographs of all known RPM varieties. In addition, the book includes detailed descriptions and cross-references. A comprehensive guide to the reed die varieties of the Lincoln cent is an excellent resource for collecting the coin. The book is a must-have for collectors who love collecting this type of coin.
Most of these dies are identical to the working versions. The master die was engraved by an engraver, and it was transferred to the working die. Until the late nineteenth century, the mintmark and date were separate pieces of the master die. Today, most modern coin dies are virtually indistinguishable from each other. However, there are instances of doubled dies, overdates, and repunched mintmarks.
To achieve a satisfactory image on the working die, the working hub was squeezed several times. This process was repeated until the image was formed on the working die. For larger denominations, this process might require up to nine or ten hubbings. The photo below was taken at the Philadelphia Mint, thanks to Arnold Margolis and Error Trends Coin Magazine.
