1990 penny no mint mark

[Guest]

Hi, i found 3 1990 pennies with no mint mark. why is the mint mark missing? are these special pennies?

No Mint Mark means it was made at the Philadelphia mint. There are three mints where they are made. The other two are D for Denver, S for Sacramento.

While a lot of the other denomination place a P mintmark to identify the Philadelphia Mint as the maker, Lincoln cents are a special case. They have never placed a P mintmark on the cent to identify Philadelphia.

Wendell and Karah summed it up nicely. If a penny does not have a mintmark, that means it came from the Philadelphia mint. The other 2 mintmarks you will find on pennies are D for the Denver mint, and S for the San Francisco mint.

There was an exception from 1965 thru 1967 when mint marks were not on any denomination and could be from any of the mints.
