I thought I'd do something crazy and try my luck on two $500 bank boxes of rolled quarters...that's a thousand dollars or four thousand quarters!!!  This turned out to be alot of fun and what I found was very enlightening...I found nothing!!!    No silver, no errors, no tokens, no slugs...nothing...  All that said, I'd do it again. Winter is coming and a project that involves coins, a glowing fireplace and a hot toddy sounds pretty good!
