There are no reports of 1977-D quarters struck* on silver planchets**.Two things to check:First, look at the coin's edge. If it shows any copper, you have an ordinary quarter.Second, if the edge is the same color as the face, compare the coin's weight to an ordinary clad quarter. A silver quarter will be substantially heavier (6.25 gm vs. 5.67 gm). Use a Popsicle stick balance if you don't have an accurate scale.If the coin weighs the same as a normal quarter, it's simply been plated for use in jewelry or similar.To clear up terminology:(*) Coins are struck or minted, not "stamped".(**) They are struck on blanks or planchets, not "plugs".
