United States: Stamp Collections & Balances
United States, 1950s-70s plate block collection,
likely over a thousand glassines organized by Scott number, with representation of issues mostly from 1958 Gunston Hall to 1974 Sleepy Hollow, an ideal lot for the plate number enthusiast, some duplication of numbers as expected, but a useful accumulation, chiefly fine-very fine.
