Back to the subject of medium value/ mid-range catalog stamps .
I think it is safe to say ,from my experience at many different stamp auctions and viewing the many WORLDWIDE COLLECTIONS ,it is safe to say 75% are filled with the low value stamps . I would not disrespect what many worked on as a life long hobby and never purchased higher price stamp ,they enjoyed what the spend their time and money on .Also most collections that appear on
ebay are these lower value stamps maybe 90% or 95% ,this would have a bigger percent of picked over or beginner collections .
So purchasing these mid-level collections are harder find ,It is also true what a poster named KEIJO on another chatboard posted in Dec.8, 2016 which also holds a lot of truth ,he said "kind of hard to image any person collecting 100K stamps would end up with nothing but common stamps " which I agree with ,there is always some mid-level stamps in these larger collections .
So a deciding factor these Stamp Auction firms figure on putting a value on any Worldwide Collection or even a large country collection is how many mid-level stamps are there . We all know if any high value $100.00 set or rare stamp is immediately highlighted in the stamp firms catalog .Stamp Auction often will pull a high value or rare stamp to sell separately , The middle range stamps are left alone by the auction house but pulled by stamp dealers and
ebay sellers to be sold most of the time as separate items .
I have to believe when Kelleher Auctions sold the inventory of A & D stamps , their inventory of 594 RED BOXES {maybe the largest inventory ever sold as one stamp auction lot } that from the price realised at auction . That someone pulled out the better mid-range items .
So it is my strong belief that better mid-level {$15.00 to $80.00 } other than buying large country collections ,your going to have to pay a per stamp or per set price for them .
