George 599

[pdv006]

Here is a question for the experts...... as you can see I have a coil of four. Between the 3rd and 4th george, there is a perf missing. On the back there isn't any Mark's for the perf. Is it a good flaw or a common boo boo. Thanks all.

Not an expert, but missing perfs on definitives of the early 20th century are not unusual. If there is sign of "indentation" on the back, then it is called a "blind perf". No mark at all, then it is a missing perf.

Although it doesn't apply for this stamp, during the world wars when use of metals was being limited for the war effort, perforation pins were often allowed to wear/break. The result is a lot of blind/missing perfs scattered throughout the pane. These types of EFOs (Error/Freak/Oddity) are sometimes called "war perfs".

For some examples of missing/blind perfs and "imperforate between" stamps, see Errors, Freaks, and Oddities.
