1 of 5 sets of 1961P Philadelphia US Treasury issued 5 coins proof sets in orig

(1 of 5) 1961P US TREASURY ISSUED PROOF SET - 5 coins in original packaging w/ treasury envelop, and where applicable the Superintendent inspection polyethelene note which only appeared in certain years. Odd verbiage in each one. Two are still sealed that Dad got direct from Treasury and another opened. Remaining two were purchased at auction in 70s with card still attached to outside envelop. Note: photo with six has one that is 1962p

*some of the 20 plastic packs appear to be have a small microcrack in the plastic where it has allowed air into the small chamber where the applicable coin is being housed, so a tarnish spot has appeared, and some are only visible with eye loop, but will be noted where I have discovered them. All packages have been left as they were stored so that they can be assessed and graded if applicable. All sets have contents that came with them from Treasury unless it is noted. Each coin has its own sealed portion and that seems to be the only part affected. Otherwise excellent condition. Stored for 4 decades with other sets from 1956-1964. All accompanying purchase receipts are included with each if purchased from coin show auction in 70s, if not direct from treasury. Most were birthday sets for my older siblings.There are additional sets which have not been cataloged yet but part of a different lot from Dads vast collection.

My Cataloged here sets are (3) 1956P, (1) 1958P w/o envelop, (1) 1959P Gem proof, (3) 1960P , (5) 1961P, (2) 1962P, (3) 1963P, (2) 1964P
