P or no mint mark means Philadelphia
However, your coin isn't a "Monticello Liberty" coin - it's a 5-cent piece issued during WWII, and made from a different metal. The design is the same as that used on regular nickels up till 2003 so it should look familiar, with the only change being to use a large mint mark to indicate the different alloy.

If it is a Mint error it may be worth a few dollars, take it to a coin dealer to see if it has any value.MoreIt's called a Jefferson nickel rather than a Monticello nickel.
