What is the Value of a nickel with 1989 on one side and 1990 on the other?

You have what's known as a "Magician's Coin".

This is NOT something that was done at the Mint.

This was made by altering two normal coins and gluing the altered pieces back together. Use a magnifier to check just inside the rim on one side of the coin -- you are looking for the seam where the two pieces were joined -- it could be on either side of the coin.

This type of novelty item sells regularly on eBay.com for a couple dollars.
