Dose anyone know why my 1965 penny dose not have a mint mark, I think that is what it is called, under the year?
Not including Halves or Dollar coins, Only Nickels, Dimes, and Quarters have the Philadelphia mint mark -Shrek
Mint marks prohibited that year http://www.usmint.gov/about_the_mint/collectors_corner/index.cfm?action=mint_marks
plus most 1965's where minted in the year 1966 anyways read under "Can you explain the policy about the dates that are stamped on United States coins?" http://www.ustreas.gov/education/faq/coins/portraits.shtml#q3
No US coinage 1965-1967 have mintmarks. In the infinite wisdom of the powers-that-be at that time, coin collectors were blamed for the coin shortage. The removal of mintmarks was supposed to keep collectors from hoarding coins.
Eva Adams was one of the powers that be, she was a very interesting person, probably had in her possession a 1964 Peace dollar.
Some more trivia on 1965's pennies but if 1965 pennies had mintmarks the US mint made the following at each mint P - 301,470,000 D - 973,364,900 S - 220,030,000
I've always wondered if there was a way to tell what mint these "unmarked" coins came from. Surely there is a known sample specimen that could be compared to see unique die features.
