EXTREMELY FINE. A PRISTINE MINT NEVER-HINGED EXAMPLE OF THIS POPULAR MODERN ERROR -- THE C.I.A. INVERT.
Popularly called the "C.I.A. Invert", a single pane of 100 stamps was purchased at a the McLean Va. Post Office by employees of the C.I.A., for use on mail from the agency. They noticed the error, pooled together funds to buy a replacement sheet and kept the pane for themselves. When it was discovered who had purchased the stamps, a scandal ensued over who actually owned the stamps. Of the pane of 100, only 93 sound examples reached collectors.
