Well talking inventory on my late father's stamp collection, I called Mystic Stamp, for which he unfortunately spent way too much from, and he had a lot of bonus points! I decided to use them and find stuff. Well, I found first day stamp covers with uncirculated modern commem uncirculated dollars and used most of the points. The sad thing about these first day covers were that the coins were encapsulated with some flimsy plastic, so I transferred them into capsules. You can see toning and some spots on the Korea commem. The good news is that I added a few more modern commems for which I usually don't collect. A little variety is not a bad thing, and I think my father would be fine in my purchase.
I sold the stamp collection, which was a painful long experience. I did have international sheets I still need to sell
