The United States Stamp Society donated a valuable prize to World Stamp Show – NY2016. The award was a complete error pane of 20 of the $2.00 Bobcat definitive plate number 1111(1) with the engraved black missing. As a result, the $2 denomination and initials USA are missing from all 20 stamps. The multicolor lithographed & engraved stamp, designed by Chuck Ripper, was issued June 1, 1990.
Listed as #2482a, each of the 20 stamps are valued at $200 in the 2016 edition of the Scott Specialized Catalogue of United States Stamps & Covers.
