Dearborn Moderator United States 94786 Posts	Posted 05/13/2023 10:52 am What kind of "plastic sleeve"? or are these all from a sealed "Proof" sets? Well #4 has a very big and unsightly fingerprint on it. They certainly look to have been 'handled' or stored badly. Collecting since 1972. Learning from then on "Tell me and I forget.

coincrew1000 Valued Member United States 71 Posts	Posted 05/13/2023 11:18 am the center of the coins in this case the bust of washington is unaffected by it but its everywhere else on the coin. Report this Post to the Staff
Cointree Valued Member United States 449 Posts	Posted 05/13/2023 11:21 am Hard to tell from photos, but white haze around the edges of proof coins is pretty common and probably formed in the original proof set. However fingerprints and the other marks I see on some of them is obviously from having been removed from the OGP and handled and now are impaired proofs. Report this Post to the Staff
Dearborn Moderator United States 94786 Posts	Posted 05/13/2023 11:31 am The fingerprints are an important diagnostic tool - it tells us that the coin were mishandled Improper storage can cause this 'milk' stains on them.

coincrew1000 Valued Member United States 71 Posts	Posted 05/13/2023 11:53 am the finger prints didn't deposit all white crap on them. I have others that don't have finger prints o them but they have the crap. need a way to remove it with minimal damage to the coin. any ideas? cuz they are worthless like they are.

Dearborn Moderator United States 94786 Posts	Posted 05/13/2023 2:00 pm I'm not say that the fingerprints are the cause of the milking issue. They only help tell the story of how they were handled in the past. Usually when the milk spots show up, there is not much you can do about it. Try an acetone soak and see what happens.

ijn1944 Bedrock of the Community United States 19115 Posts	Posted 05/13/2023 3:22 pm I've seen similar in late 60s/early 70s proof coins in 'unopened' packaging. The packaging isn't always 100% air tight. I had a '71 set which appeared to have been in a high humidity/high temperature environment for some time. The coins were cloudy and a couple had a 'bullseye' discoloration pattern. Report this Post to the Staff
coincrew1000 Valued Member United States 71 Posts	Posted 05/13/2023 8:55 pm Coin dealer called them milk spots. a little muratic acid and anti-tarnish gold and silver polishing cloth. They are shining again. All is well. Finger prints are gone too. Edited by coincrew1000 05/13/2023 8:56 pm Report this Post to the Staff
Dearborn Moderator United States 94786 Posts	Posted 05/13/2023 9:04 pm good to hear - can we see some after pictures? I have not heard of this procedure before, can you explain it please?
