Today I picked up a box and inside I found a few rolls that had pennies individually wrapped in what appears to be saran-wrap/plastic food wrap. I'd say I found 5 like this. Since all of the coins were BU from the 60's, I'm assuming this was some collectors attempt at protecting the coins from fingerprints or dirt. Anyone seen this before? Wouldn't that actually hurt the coins over time?
Also in the box were rolls of 1973S, 1962D and 1961 all BU. Would these be worth anything or should I just keep them for the copper?
