US #1305E 15¢ Oliver W. Holmes

1978 Mint Mis-perforated Pair
Although errors can hardly be called "perfect", you have to admit that the perforations on this mint coil pair couldn't be more misplaced - perfectly down the center of the stamp! The error creates a new design, moving the portrait of Holmes to the left and the denomination to the right, and you can add this startling error to your collection at a great price!
