The 5-cent Gatun Locks stamp has a spelling error that was discovered too late and is on all stamps. The Spanish word for locks is ESCLUSAS, but it was incorrectly spelled EXCLUSAS. This stamp was ABNCo order F 4243, which is engraved on the selvage at the top of each sheet. From the archives of the ABNCo sale we now know that the printing date was June 19, 1914. The Canal Zone ordered 100,000 of these stamps. No major errors have been reported for this stamp, although the un-overprinted version produced for Panama is known with the center inverted.
