That's the mint mark. It tells where the coin was minted. Many but not all coins carry a mint mark. Coins without a mint mark are from Philadelphia.
S = San Francisco
D = Denver (1906-present)
P = Philadelphia (1980-present, 1942-1945 on nickels)
O = New Orleans
CC = Carson City
plus a few other branch mints that only struck gold coins
The only difference is it has a P on the back of it (Opposite of the face)
Yes it’s a 1943 Jefferson Nickel silver with the capital ( P) over the monticello building . It. Has a slight discoloration on both sides and along the outside cercomphrance it has a couple of very small ding’s . All letters and numbers and face and back appears to be in good condition
That is what is known as a war nickel, because nickel was needed for WWII, it was needed to change the composition of the nickel to one including 35% silver, as of the time of writing, your coin is worth $1.64 in silver content alone.
Monticello is on the back of the nickel because it's one of the symbols most associated with Jefferson. He designed the house himself and it contained a number of innovations that were ahead of their time.
Come Back to Sorrento - 1943 was released on: USA: 1943
Back from the Front - 1943 was released on: USA: 28 May 1943
It's worth about $2.00 just for the silver maybe more, but it depends on the grade of the coin.

No, Jenna Jameson is not in Nickel Back. She is a porn star and writer. Nickel Back is a popular rock band.
??? Pennies are 1-cent coins, nickels are 5-cent coins. Saying "penny nickel" is like an "inch foot" and doesn't mean anything. Please post a new question after you determine what you have, including its denomination and mint mark (on a cent, there might be a D or S under the date, on a nickel there will be a P, D, or S above the dome of Monticello on the back)
