1776 Quarter?

Recently a classmate of mine discovered a 1976 quarter dollar in his change. Because of the dual dates he thought it was a 1776 quarter and a rare coin. I could hardly believe that only 35 years later this very famous and widely publicized coin is now virtually forgotten among the general population. Then again, it isn't very valuable in general but especially not in low grade because hundreds of millions were made in the two year span of minting (1975 and 1976). As mentioned in an earlier post about these quarters there is a silver set that is worth about $30.00. Of course, that is for an Eisenhower Dollar, Kennedy Half Dollar, and Washington Quarter Dollar in UNC, with the one year only (more like two years) design, and is made of 40% silver.
