SuperPoacher74 Valued Member United States 115 Posts	Posted 05/31/2018 08:17 am * Edited by Staff to Add Year / Mintmark / Denomination to Title. Titles are Important! * I just yesterday grabbed this coin. Upon close inspection it's in my opinion it's about MS50-55. But it has such a strong discoloration. it is possibly tarnish but I dont think so? it's not paint. Looks to be black with a white almost corrosive outline? I still think it's a beauty but I'm curious. Thanks for any replies. Also can someone please tell me how to rotate my photos in the image optimizer? I don't see an option.. Thanks much!!

chafemasterj Pillar of the Community United States 6514 Posts	Posted 05/31/2018 09:32 am I believe to rotate your pictures when your full image is first on the screen, prior to hitting 'Crop Image' there are two curved arrows in the top left corner. Rotate right or left. Check out my counterstamped Lincoln Cent collection: http://goccf.com/t/303507 Report this Post to the Staff
Spence Moderator United States 34410 Posts	Posted 05/31/2018 09:46 am @SP74, it looks to me like this coin may have been plated and now this surface layer is peeling off. Are you sure that this guy is actually silver? Also, a small thing, but the MS in a grade means "mint state" and once something is circulated then it no longer is mint state. A better way to describe your piece would be "AU50-55", although I will leave it up to others to provide opinions about the grade.

dsfreeworld Pillar of the Community United States 4337 Posts	Posted 05/31/2018 09:55 am looks harshly cleaned, note the heavy lines throughout especially on the obverse I'd vote environmental damage to the surface at this point due to the layer of sulfide being stripped from the cleaning beauty is in the eye of the beholder so that's good news Report this Post to the Staff

Rotate right or left. Correct. You have to hover over the upper left corner of the image to get the rotate tools.

SilverDollar2017 Pillar of the Community United States 8715 Posts	Posted 05/31/2018 10:18 am This coin has been harshly cleaned. Hairlines on both obverse and reverse. The strange coloration reduces the eye appeal to a very low level. This would grade AU Details. Report this Post to the Staff
Conder101 Bedrock of the Community United States 17884 Posts	Posted 05/31/2018 11:10 am Anything that reacts with the metal can cause a discoloration. being able to tell you the specific compound that causes the discoloration on any specific coin is probably not possible, at least without detailed chemical analysis. In general most things that react with silver and sulfur or chlorine bearing compounds or nitrates. Report this Post to the Staff

just carl Bedrock of the Community United States 20753 Posts	Posted 06/01/2018 2:43 pm Still sort of a nice looking coin. And you could simply tell people to just lay their monitors on the side. Edited by just carl 06/01/2018 2:45 pm Report this Post to the Staff
