Coin Collectors

I am new to the forum and have a question about a coin i found several years ago in central Florida while metal detecting. The coin appears to be a store credit type coin, there is no date, only the company name (H.G. Crenshaw) and good for 50 in merchandice. it is a bronze colored coin and appears to have been snipped on one edge by a pair of tin snips. I found the coin alongside the reminants of what appeared to be an old apothicary wagon. I found the steel bands of the wagon wheels, and also several old medicine bottles. Any information on this coin would be greatly appreciated. I will try to post pictures of it tomorrow. Thanks all.
