Once I saw some nice American large cents and other old coppers that had been left loose in a box with foam padding for 20 years... they had bonded... when it was removed with acetone, the coins were pink and pitted where they had touched.

You might think that, but a lot of foreign mint and proof sets from the 60's and 70's often used materials that would damage the coins. Especially things like heavily plasticized PVC. I've seen many a world mint set with the coins covered with heavy green slime. Report this Post to the Staff
