This collection consists of PROOF SETS 10 of each: 1961, 1962, 1963 and 1964 and SPECIAL MINT SET 5 of each: 1965 and 1966. 61, 62, 63, 64 come from Philadelphia.
65 came from San Francisco. They all have the Cardboard, COA and Envelope except for 1964 none of the ten packs have the COA not sure why, personally I think it was some kind of OOPS.
None of the plastic or cellophane has been open. If I missed anything please let me know and feel free to ask any questions you may have. I do have a couple more coin auctions.
