You should direct your question to Clem. He dollar averages his costs over several HUNDREDS OF $$ (if not thousands) in play to determine price.

As for your question; "How do we just sale them for $10?" Answer; Because many properties no longer redeem silver strikes anymore and have done away with the machines and some folks would rather salvage SOMETHING from their expense. Have you ever sold something for less than what you paid? Most of us have!
