Rare, Mint condition First Editions of discount Important US Coins Set; 1932 Washington quarter, 1946 Roosevelt dime, 1938 Jefferson nickel etc

[My dad passed last September at the age of 96 and among the items I inherited - aside from the collector's gene, which in my case tends toward books and vinyl - is a significant part of his coin collection. My goal here is to offer these at below-market rates discount while not too severely undercutting their worth, in the process (in theory at least) making both buyer and seller happy.]

Item offered here is pretty much all there in the picture, and photos, and the title. I was unable to determine exactly when this (very cool) set was itself issued but as it's latest minted 1st edition coin is the Susan B Anthony dollar in 1979 I'm assuming it wasn't long after that. All coins appear uncirculated and, in what seems a rare pairing, are matched with theme-adjacent postal stamps. Some of those are concurrent with the coins they're matched up with (the Kennedy half dollar, for instance), others vary (the Anthony stamp predates the coin by 43 years, the 1938 Jefferson nickel is matched with a stamp from 1960.

All in excellent condition.
