HELPFUL HINTS...

   Determining the attribution of an RPM includes three basic factors - the spread of the secondary mint mark, the distance of the mint mark from the date, and the markers on the rest of the coin. All must match to be certain that the coin in question belongs to the listed die.



  Cleaning coins is defined as any treatment that moves the metal on the coin in any way. This can be anything from chemical acids to abrasive cleaners. There are safe and effective ways of removing dust, dirt, and grime from copper coins. Acetone is one of the most common chemicals used for this.

Recently added information

This site is a constantly changing work in progress. On a regular basis we add images and die information to the database. The home page of the site shows a total number of die varieties and images that reside on the site, but it doesn't specify which dies were updated. With a site of this scope, it would be nearly impossible to find all the new information each time updates were made without some help. That is the purpose of this page.

Below you will find two lists. The first one covers all die information added in the past week, and the second list covers the additions made up to a month ago.
