I'm not an error or variety collector (in fact, as my user name implies, I'm not much of a collector in general), so I humbly request help from those who know more than me. Recently I found a 1995 quarter with virtually no reeding: there's only the faintest hint of it on a small portion of the edge. The rim of the coin appears intact and the diameter of the coin is right, so I don't think the reeding has simply worn off or been grinded off. I've Googled for 'filled collar die errors' and similar phrases, but they didn't turn up anything. Assuming I successfully attached the picture, you can see the edge of the coin, sandwiched between two normal quarters for contrast. Is this an error of interest or should I just use it as a down payment on a Coke?
