I also am compiling a set of the quarters.
With searching all the known hidey holes for change and purchasing 100.00 from the bank, I came up with
1 shy of the P set (Hawaii) and right about half the D set.
I intend to roll search till the set is complete, then cherry pick until I get the higher grades.
Other than that, if I decide I want to be a bit more ambitious with my cash flow, I might buy them from the dealers, flea markets, or
ebay.
I am considering putting together a pf70 slabbed set or maybe acquiring a few slabbed ms70's
