1901, 2¢ Pan-American, Center Inverted, o.g., nicely centered and bright with unusually rich color, almost invisible tiny tear at bottom, otherwise fresh and F.-V.F.; with 1999 P.F. certificate. Scott No. 295a $55,000.
AN DESIRABLE EXAMPLE OF THIS RARE MINT INVERT WITH ORIGINAL GUM AND.
The 2¢ is the rarest of the regularly issued Pan-American Inverts with probably no more than 200 being issued based upon the fact that two distinct shades exist of the error, and therefore two panes of 100 were released. Current estimates show that less than 100 examples have survived, including about a half dozen used singles and two mint blocks (one rejoined).
Scott also states that "almost all unused examples…have partial of disturbed gum" and values the stamp accordingly. This invert is also normally found with pale color, unlike the example offered here.
