Yea, kind of. I have SOOOooo many duplicates, so I am only keeping my mint stamps and only my unaddressed first day covers, unless I dont have a duplicate of it of course. But as I get an unaddressed, out goes the addressed one! I'm a hoarder lol! I have 2 cabinets 6' x 3' full and like 6 or 8 banana boxes full of stamps or related materials..... I GOTTA thin out!
