4c Pan-American, Center Inverted (296a). Unused (regummed), bright color, rebacked, repaired and reperfed at top

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.

With 1990 P.S.E. certificate
