TJLang Valued Member 424 Posts	Posted 11/12/2018 1:42 pm I think moisture trapped in the 2x2 could cause this. JMHO Report this Post to the Staff
Boxcar12 Valued Member United States 155 Posts	Posted 11/12/2018 1:50 pm Would it be better to clean them or leave them? Report this Post to the Staff
BigSilver Pillar of the Community United States 2843 Posts	Posted 11/12/2018 2:16 pm These have nearly no numismatic value. They are pretty much just bullion. Cleaning won't make them worth more, nor less. You could try acetone which is not regarded as cleaning by most collectors. Report this Post to the Staff

T-BOP Rest in Peace United States 18456 Posts	Posted 11/12/2018 5:28 pm since they are basically bullion I would dip them in silver dip , just long enough to do away with most of that black . Report this Post to the Staff
Boxcar12 Valued Member United States 155 Posts	Posted 11/12/2018 6:22 pm Thank you I have a bunch but only about 10 have the black. I will try acetone first as I have it on hand. Report this Post to the Staff

Coinfrog Bedrock of the Community United States 94367 Posts	Posted 11/12/2018 7:58 pm Might as well dip but hardly even worth the effort. These are just bullion coins at this point. Edited by Coinfrog 11/12/2018 7:59 pm Report this Post to the Staff
Boxcar12 Valued Member United States 155 Posts	Posted 11/12/2018 8:39 pm The holders came from the 1960's at the latest that my grandfather used. He may have had them from years before as he never threw anything away. Report this Post to the Staff
