U.S. Possessions

This section illustrates plate number material for overprints on regular U.S. issues.

Canal Zone (1904-1938)

Stamps specially prepared for use in the Canal Zone superseded the overprinted U.S. issues in 1938.

Overprints of the U.S. 1902-03 Second Bureau Series

Except for a single strip of the 5 value with a Right side plate number, these overprints are known only on LL panes. Therefore all plate number positions are L or B.

Overprints of the U.S. 1926 Fourth Bureau Series, rotary press issues

Perforated 10

CZ Scott 97, 2, plate number 18827 (on U.S. Scott 583)

2¢ was the most common rate for local mail within the Canal Zone, so it was logical that the 2¢ Rotary stamp would be overprinted.

CZ Scott 98, 3, plate number 18446 (on U.S. Scott 584)

The flat plate 3¢ value was not overprinted with either the "flat top A" or "pointed A" series, so this was the first of that denomination available.

CZ Scott 99, 10, plate number 18538 (on U.S. Scott 591)

Perforated 11 x 10-1/2

CZ Scott 100, 1, plate number 18731 (on U.S. Scott 632)

CZ Scott 100 var, 1¢, overprint shifted to left, plate number 18730

CZ Scott 100a, 1 overprint omitted error, vertical pair, plate number 18730

Only 10 vertical pairs exist. This pair with the plate number is unique.

CZ Scott 101, 2 used, plate number 18985 (on U.S. Scott 634)

CZ Scott 102, 3, plate number 18803 (on U.S. Scott 635)

CZ Scott 103, 5, plate number 18855 (on U.S. Scott 637)

CZ Scott 104, 10, plate number 19235 (on U.S. Scott 642)

CZ Scott 116, 14¢, plate number 20549 (on U.S. Scott 695)

So when the dust settled, all denominations of the Fourth Bureau Series were overprinted in some format except: 4¢ (either Martha Washington or Taft), 6¢, 7¢ 8¢, 9¢, 11¢, 13¢, $2. and $5.
