Correct ...you would have to send in the whole tube unopened for this "special" label...it does exist
It would cost $17 x 20 + $5 x20 + $10 + shipping both ways..chances of a profit from selling 20 slabbed bullion
ASE's might be slim but you can do the math
MS69's are in the $45-60 range. The 70's have a wide range of prices with a bunch with Mercanti/Trump/etc mudding the group. Hard to tell on that price
Depending on the number of 70's you get it might work..big maybe
