These are ordinary Tennessee state quarters altered by a private company to add images of Elvis on one or both sides. They're not official Mint products and are considered to be altered coins with no value to numismatists. You may be able to find a buyer among collectors of Elvis memorabilia but so many were made that they have very little aftermarket value.
It's an ordinary Tennessee state quarter that was "colorized" by a private company and sold as an "instant collectible". Coin collectors consider colorized coins to be altered or damaged items with no additional value, but collectors of Elvis memorabilia may pay a small premium. Unfortunately there are so many of these items on the market that they rarely resell for as much as their original cost.
