They are not plated, but rather a consistent 90% silver alloy throughout the coin. Quarters dated 1965 and later don't contain any silver.

Do coins now contain silver?
Circulating coins are no longer made of silver anywhere because the price of silver changes every day. If coins contained silver people would "game" the price changes by alternately buying and melting the coins, skimming the difference as profit. However many countries make silver, gold, and other precious-metal coins for collectors and investors. These coins are priced according to the amount of metal they contain and aren't designed to be spent.
