Put it into perspective Coop. A candy bar around here is about $1.50. Maybe a dollar on sale. You go to a machine to buy a pop and it's $2.50. A bag of chips in the machine is about a dollar.
So; you read about the floating roof, you want a floating room and you take your $5 and buy one for a buck, then use your change to buy a Pop and a bag of chips.
The $5 to $7 for a red unc is...well...about a buck more than I would charge for a 69D red/unc. Mind you, I don't put thumbprinted, baggy or heavily carbon spotted coins in my cases. And..yes I do have "young collectors discount".
As for copper prices I pay 2 cents for
LWC and I wholesale them for 3 cents to one of the big boys.
