I received about 45 Proof sets from my grandparents when they past away many years ago. I am just looking for a way to document what I have in a system. None of these are certified in any way but they are all still in original packaging. So I have something like a 1975 United States Proof Set which I would like to add, but I have no Idea how to go about adding them to my inventory. These are all basically brand new still in their packaging. Any help would be great.
