I've never been to a scrapyard so some of this may sound naive
Let's suppose it's June 30, 2014, a couple months after the gov't decided to officially lift the melt ban on copper cents. If a person showed up at their local yard with say 250 lbs of sorted cents, how would the buyer know whether the coins were in fact pre-'82? There could potentially be a lot of room for error in that many coins I would think.
Would they have to be counted by them and then weighed?
Just curious...
