I'd appreciate some advice that I can pass along to those who will eventually
inherit my stamp collection. None of my children and grandchildren are stamp collectors.
I think mine is an unusual – if not unique – collection. I collect worldwide postally used stamps on which I can ID the city/town/place of cancel. In the several decades I have been trading dupes with other collectors, I've not found anyone else doing exactly what I'm doing.
I differentiate among the various spellings and punctuations of those place-names. I differentiate among all the differently named entities that have had stamps issued for them. I also differentiate among those entities as being colonial or independent places. At the moment, I have more than 74,000 stamps in this collection and get more almost daily. They occupy 40 large home-made loose-leaf albums that fill a bookcase.
I pay no attention to stamp values or varieties. There is duplication of individual stamps, as I am primarily seeking discrete places of cancel rather than discrete stamps. Some are definitives, some are commems. Most are singles; some are pairs or more. Most are off, but some are on paper. Sock-on-the-nose cancels are plentiful, but many of the stamps bear only partial but ID-able cancels. Many of the U.S. are stamps with the place-of-cancel dial next to the stamp, as that was the way most U.S. machine cancels have been applied.
So what can I suggest to my family for the eventual disposal of this collection if none of them chooses to continue the collection?
