THE UNIQUE USED BLOCK OF FOUR OF THE 1917 11-CENT WITH ALL FOUR POSSIBLE PERF 10 ERROR VARIETIES. ONE OF THE MOST OUTSTANDING RARITIES OF 20TH CENTURY PHILATELY.

Many examples of the Perf 10 on One Side rarities show transitional perfs from 10 to 11 or from 11 to 10. This is because the out-of-gauge perforation pins would frequently cross the span of more than one stamp. Depending on where the wheel contacted the sheet, it is possible for surviving multiples to show a combination of Perf 11 and Perf 10 stamps or transitional perfs on one stamp. The four possible varieties are Perf 10 at top or bottom and transitional Perf 10/11 at top or bottom. This block is remarkable as the only certified example with all four varieties se-tenant and no normal stamps. The Galveston duplex cancel, rather than a precancel, only adds to its rarity.
