To fill up a 7070? hmmmmmmm That totally depends on grade of coins you obtain. I finished one a couple of months ago with generally XF or higher (Early large cents and
Half Cents excepted) and I'm guessing around $4K. I haven't kept a close record because the wife might find it!!

. I do have another 7070 and I'm thinking, at some point, of going lowest grade possibles in that one. You might say I have too much free time on my hands!
