VERY FINE AND CHOICE ORIGINAL-GUM EXAMPLE OF THE ONE-CENT PAN-AMERICAN INVERT.
The 1c Pan-American Inverts were found in at least four different post offices around the country. Of the 600 to 700 known, most have disturbed gum and are off-center. The example offered here is remarkably fresh.
With 1971 P.F. certificate. With 2005 P.S.E. certificate (f-VF 75; SMQ $7,000.00 as 70, $10,500.00 as 80)
