I'd rather keep my copper than sell at this price.

If he used 7,350 pennies as 50 lbs then:
Selling price shipped = +$98.00
eBay Final value fees = -$8.82
Paypal fees = -$3.14
Cost to acquire pennies = -$73.50
USPS medium flat rate price = $10.50
Profit = +$2.04
I don't know Florida's copper percentage, but using 28% as a gauge, it would take 10 1/2 boxes to acquire 7,350 pennies. Even at 4 boxes per hour with a Ryedale that's over 2 1/2 hours of just sorting them.
I sort with a Ryedale sniper as a hobby, so I do understand that there is no big hourly profit to be made unless you go the multiple Ryedale apprentice route, but this seller is obviously looking to make at least some money since he put them up for auction on eBay. Did he try an attractive starting price to entice bidding? Perhaps. IMO that is not the way to go. If I were selling my pennies my practice would be to start the auction at the lowest reasonable price I was willing to accept in case I only get one bid.
