FINE APPEARING 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. (Image)
FINE. A SCARCE SOUND ORIGINAL-GUM EXAMPLE OF THE 4-CENT PAN-AMERICAN INVERT.
The 4c Pan-American Invert was a special printing and not regularly issued. Examples were distributed through two official channels, and the gum on the majority of stamps without "Specimen" overprint was disturbed. In fact, because the stamps were removed from mounting paper, they are generally thinned or have seriously disturbed gum.

VERY FINE APPEARANCE. A PRESENTABLE AND AFFORDABLE EXAMPLE OF THE RARE 4-CENT PAN-AMERICAN INVERT.
The stamps were mostly removed from mounting paper, and so many are defective. On the other end of the quality spectrum is the example graded 90, which we sold for $625,000 hammer in our 2008 Rarities sale.
