Hello everyone, bought a box of pennies and found these two pennies with no date and was wondering what makes these pennies turn out like this? Is it because they have gone through the coin machine's to much? First three pictures are of one penny The last four is a different penny Thank you
Correct. Post Mint Damage. Known as dryer coins. If all copper then they are pre 1982. Copper plated zinc then minted post mid 1982.
