I'm not entirely sure what I have here. It wasn't in the 2012 Redbook I use, and a very quick google search also showed nothing. There are listings for 1857 No mintmark and 1857 O, but no S for those years. S mint does show up in '56 and '58. I'm going to try to post pictures. I don't know how you guys happen to get picture perfect close ups of these tiny coins, maybe it's the camera, or maybe it's some skill I don't possess, either way, these pictures are not that great, and I apologize. The first two pictures on the table show the die orientation, which is slightly off. I would like to know what this thing is, mintage figures (if available) and yeah, I suppose value too. I'm slightly perplexed.
