It is a very large hobby in Europe. Unfortunately our younger generation have no interest.
The demand side is shrinking. The Baby boomers now what to get rid of their collections as their kids do not want them. So the supply side is growing very fast.
I have been a collector for the past 60 years. Inherited 2 collections.
If I sell them individually they will be in very good condition.
If I sell the entire collection, it will be as a mix nag. majority will be in very good condition.
I am not a stamp dealer.
I have never sold a stamp.
Between years 1980 and 1990 I spent $20,000 (Can. $s ) buying stamps and first day covers.
