Hello,
I finally found out which article the error coin appeared in. The coin is in the March 27 issue of
Numismatic News. Page 32. An article by Ken Potter discusses errors being found on new dollar coin edges. I'm mentioned by name (Garrett Reich) and the picture I submitted on this thread is the same one that appears in the article. Now I just need to figure out how to sell the coin for the best price. Suggestions or offers welcome.
