If it is a "S" mint one, it maybe a silver planchet proof coin. But as mention some TV hucksters are selling gold/platinum
State Quarters for a premium. People realize they were sold something not collectable and spend it, or the coins are stolen and just cashed in. Even proof coins get back into circulation. Proof coins are very shiny. Compared to a business strikes, even a camera can show you the difference.

So check for the "S" mint mark and let us know what you find.
