VERY FINE. A RARE PART IMPRINT EXAMPLE OF THE 1904 8-CENT ON 50-CENT BISTER BROWN CANAL ZONE ISSUE FROM THE RIGHT COLUMN WITH SINGLE 15MM "PANAMA" READING UP.
Only 50 of this issue with "Panama" measuring 15mm were printed. This example from the right column with single "Panama" was the result of a shifted ovpt. and is presumably one of only 10 that can exist. The part imprint adds to its desirability.
With 2004 P.F. certificate. Scott Retail as normal No. 15 with 15mm "Panama" without premium for the extra variety
