First, I assume these are all same date rolls(all 50 are1964D, etc). I too buy OBW LMC's. Depending when and how first put up from original bag, tubes ( brand matters), paper(matters) foil wrapped inside paper(absolutely best). Not all coins seem to tone the same way, at same rate, even per side. Never had wax trouble, then again never buy rolls off eBay either, just won't do it! Get mine in on line auctions. Have heard wax is cheaters way of trying to repair what I described above, don't take that to the bank tho, don't know for sure. Hint: if you're looking for gem quality high MS, not on eBay!
