My dad was an avid stamp collector. He had an impressively large collection and spent many an hour working on his collection. Several months prior to his death he turned the whole collection over to an auction house who sold it piecemeal. Interestingly, my sister and I received almost exactly the amount of money that he said that we would. After his death 10 years ago, my sons were upset then and remain so even now that the collection was sold off as they saw the collection as part of their grandfather and to not have a part of the collection was to have a part of him.
With that in mind, I will have both boys select a given number of watches from my collection and the rest will be sold by auction or with the assistance of watch buddies with the proceeds to be given to charities of the boys' choice.
Remember, these pieces of art are part of us and may be seen as such by our families and as such they should be allowed to have some rememberance of us and our passion.
