Just a side note to the large decrease in the stamp market . It is due to collectors are building smaller collections ,what we see now is a more specialized collecting interest plus nobody today is shoveling money into material that they are thinking values are going to continue to rise .
I see stuff now at auction that 40 even 20 years ago would sell at much higher levels ,one area that years ago I never could find selling cheaper than full catalog was German Colonies but in the past three years I watched and purchased many collections selling between 1/3 to 1//2 catalog for better stuff . Same with Swiss Canton issues now selling for 1/2 of 1990's prices .
The one area that I see that has gone up are low value stamps mounted on album pages or on stock sheets ,years ago it would be a surprise to see this stuff sell at 2 cents a stamp but now these same pages sell for 8 to 10 cents per stamp and sometimes sell at higher levels on
ebay . Those prices have climb higher . I am crying now on how many sets of Scott International and Other W.W. albums I cut up to get them into my $12.00 mixture boxes ,each had 300-400 stamps on cut up album pages .
