I found a 1990 penny with no s or d on it. I had the obvious question is it a proof penny. I attached pic to this posting if you could give me your opinion. Thanks

Hi Jackie,

Thank you for the pictures.

Sorry but yours is just a regular 1990 business strike penny, made at the Philadelphia mint.  It is normal for there to be no mintmark on all pennies made at the Philadelphia Mint -- it's considered the main mint, and traditionally only the branch mints (like Denver and San Francisco) had mintmarks added to their coins.

If it were a proof, it would have a mirror finish to the flat fields -- it doesn't look like yours does.

If you have a local coin shop, ask them to show you a 1990 proof set (or any other from the 1990's), and compare your coin to the one in the proof set -- you will see a huge difference.

I hope this helps,

My strong familiarity with all U.S. Mint coins, extensive reference library, and close relationships with many other dealers allows me to identify just about any coin made in the USA. I receive regular updates to all the current price guides -- both wholesale & retail -- to provide accurate values. So, with a good description or pictures, I should be able to identify and value any U.S. coin you have.


I've been a coin dealer since the 1980's and a coin collector since the 1960's. I specialize in U.S. Silver Coins and have an active online website -- The Working Man's Rare Coins -- -- offering information and inventory in U.S. coins.
