1 cent. It's a novelty item made privately.
The state was stamped on it after it left the mint. It has no collector value -- novelty value is perhaps 25 cents.
The outline of the state of NJ was added after minting. I have a frame on the wall of my study that has a penny for each state and the outline of each state has been put on each penny. It's a nice and pretty display, but the coins separately are only worth a penny. The entire state collection in a nice presentation would be worth maybe $40.00. You may find individual states in a coin dealer's misc. bin for a quarter apiece.
Only if you have the other 49 pennies in the set.
Kentucky
1¢ It's a novelty item made by a private company by altering a genuine cent and selling it at an inflated price as a "collectible".
William H. Seward

There is no one particular state that is double stamped -- it could happen to any of them.
Lincoln wanted the south to come and be a united state again.
If it is a penny, then it has to be.
One cent. It's from a set of coins sold by a private company that took ordinary pennies and stamped them with little pictures symbolic of each state. They were sold as so-called "collectibles" but don't really have any value on the secondary market. Coin collectors consider them to be damaged goods.
One cent. It's a novelty piece made outside of the Mint by stamping a little image into the coin's obverse. These are available in bulk as giveaways and promotional items, but they have no numismatic value.
