1936-1964 Rattler Proof set
Seeking advice. I am more than halfway done with a set of proofs 36 to 64 in old rattler holders. I was trying for a difficult set, but I think I may have bitten off more than I can chew. I have hit an roadblock, and the ones that I am missing are getting increasingly hard to find. At what point do I give up? Are there any proof LMC in ratters at all? or am I seeking something that does not exist? Is it even possible to complete this set?
