Yeah, the Local Coin Shop, doesn't have room for their many Modern Silver Proof Sets, so they break them open, sell the Silver, and give the non-Silver, Cents & Nickels as change. They must be doing hundreds, at a time, from time to time. Crazy, but true. Old, established, LCSs, are the best. There must be many, in the NYC, area, if you're, ever, in the neighborhood. I scored these Silver(90%) Quarters right before they busted them OPEN, last year. $5 each ($ 25 USD). Today would be $31.25.
