I buy stamps in local auctions in İstanbul for more than 15 years.  I add about 10 000 different stamps to my collection every years. I have abundant many different duplicates to exchange. But I dont have proper exchangers who have much many stamps.

I am interested in mostly used stamps which are good postally cancelled and especially stamps over the year 1985. Otherwise I have to use wantlist to exchange. I can easily get the other stuff like fdc, covers etc in our weekly auctions to exchange with the stamps.
