Phil I sometimes wonder about this too.
Personally I've spent a few thousand on my stamps over
the years. Probable worth now perhaps only hundreds,
depends I guess on how they will be disposed of.
My wife and grown children are under no illusions that
hubby/daddy has a million dollar collection.
They know that it's worth "something".
They also know that it's my hobby which I enjoy and
money doesn't really enter the picture.
Over the winter the wife & I have been going to just
about weekly estate auctions usually held in community halls
in our area and I'm very surprised at the low prices realized.
Porcelain, Glass ware, crystal, paintings, prints, furniture, etc
etc. all going for way less than I believe it would have lets say 30 years ago.
And I think it's the same with stamps.
I'm hoping that when I'm gone they will either sell my stuff at
one of these estate sales or even a garage sale instead of dumping
it.
But who knows...and who cares when you aint here no more.
