The mint made many millions of regular 1997 P nickels.
There were only 25,000 matte proof nickels minted.
They were released in the 1997 Botanic gardens commemorative
set. It would be very rare to find one in circulation.
If you have them side by side you can see the matte proof
will have a satin look over the complete coin.
