Counterstamped Coins â The References. January 12, 2013 By Leave a Comment. Ever since I brought up the topic of counterstamped (or countermarked) coins in my earlier blog post, Counterstamped Coins â Twice The History, the responses, questions and comments have flooded in. Apparently there is a large following of this very interesting sub-genre of collecting, and a severe lack of material on the subject. At least, thatâs what I understand from the responses that Iâve received. Counterstamped coins were never a focus of my own collecting. They were always more of a curiosity, something occasionally encountered at a show or shop, an enigmatic circle of copper or silver that someone long ago put their name or business to in an effort to drum up some business.
