Unopened Sealed 1956-1957-1958 US Mint Silver Proof Sets. Lot Of 3 Proof Sets

  

Lot of 3 sealed unopened proof sets 1956, 1957 and 1958. Envelopes in excellent condition except the 1957 set has a small clean cut along one side edge only, near the middle of that edge.

This appears to be a small accidental scissors cut when envelope used for packing the set was opened, about 1 inch long. The cut is too small for the set to have been opened or seen through this small opening in the envelope.

See extra photo of the set showing this edge.
