Well....yes and no. In 1976 just over 8 million Bicentennial quarters were Silver Clad, along with about 17 million Copper-Nickle clad, after that, it was not until 1999 that the issue of State Quarters, DC & Territories Issues and the National Park Series began, quarters being of Copper-Nickle Clad Copper EXCEPT that each issue of quarter ALSO had a smaller mintage of Silver (0.900) quarters, example being the 1999 Delaware State quarter. 778,437,359 were minted of the Copper-Nickel Clad Copper type, with the further mintage of 804,565 made of 0.900 Silver. I wonder if the Silver ones ever made it into general circulation, I'm thinking not?. For dimes somewhat the same thing, 1965 through present they were and are minted of Copper-Nickel Clad Copper EXCEPT that from 1992 thru 2013 there were also Silver dimes minted as well, all of the San Francisco mint, example being; 2010 s; 1,103,815 clad, with an additional 849,600 silver. The numbers I am using here come from a September 2015 issue of U.S. Coin Prices Mag., Last year of issue that I know of that showed the number of coins for each date and mint mark that were made. Comes in handy. So...again yes and no. They are out there, somewhere, but lots of fella's on this topic put out some really good reasons of why so scarce now. To find just one Merc puts a smile on your face anymore.
