Check the edge of the coin for a date.
All circulating quarters dated 1965 and later, and most proof quarters, are made of copper-nickel. They don't contain any silver. If you found it in change and it has a D or P mint mark, it's only worth 25 cents. If your coin has an S mint mark, it's a proof coin that was made for sale to collectors. If it has a copper-colored edge it's also made of copper-nickel and might sell for $2 to $10 as of 05/2010. If it's in a special holder labelled "Prestige Proof", then it IS a silver coin and is worth $8 to $17.
Depending on the coin and the pin, it would be most likely that the coin is much heavier.
