I have loads of 1982 BU zinc pennies that have these bumps on them. Does this make them undesirable for collecting?
In 1982 I worked in a quik trip (like 7-11) store and noticed that the penny was being changed from copper to zinc. So I grabbed about $50 that came in bank rolls some being zinc and some copper. All of them are virtually flawless except lots of the zinc pennies have these bumps.
