Does anyone know much about selling coins? I have face value about $170 of circulated pre 1964 quarters and dimes (90% silver) that I want to liquidate. I was considering just walking into a local coin shop to sell them in bulk but I'm not sure what fair value might be. I've checked pcgs.com, but those prices are based on rated coins at auction. PCGS is 24x face, the melt value of the silver is currently about 8x face, I paid about 2x for them last month... what price should I realalistically hold out for?
