Error coins are hot and getting hotter! Are you an expert? Do you know all there is to know about errors? How to identify, what they are worth?
The following is a list I have compiled of errors that affect the value of a coin. Anyone that wishes to comment on or contribute to this list, please do so. This list will be compiled into our coin collecting software and will impact the price shown against the grade of the coin plus error(s). Any help in adding to this list or correcting it will be greatly appreciated.
Our software is available as a BETA at http://download.coinweb.org/ free or on CD-ROM at $6.95 to cover costs of materials and at www.janschwenk.com clicking on “Coin Inventory Beta”. Please register the software. We ask that you give us your suggestions, ideas, comments, brickbats, and whatever. We want to make this the best possible software. Anything missing, tell us and we will add it. The goal of this software is to give the collector the information and knowledge he needs and the organization and tools to use it to his advantage.
Thanks!
