Stamps (Philately)/Monogram on back of stamp


Star monogram
Star monogram  
Hi Terry,
I just acquired a U.S. 84 cent newspapers and periodicals stamp
(see attachment) that has, on its back, a small monogram of a six-pointed star surrounding the letter "P" (See attachment). Is this an expertising mark, and what might it mean? Thanks for your help.

Hello John,

Thanks for your question.

It was just this morning that I was moving some of the stamps in a stock book I have and they had the same mark.  I know of no official listings for the mark.  I once thought maybe the mark (as the Star of David) was used in POW correspondence, but I have discovered nothing to support that claim.

I wish I could help you out more.

I have been involved in philately for most of my 56 years. I specialize in United States Issues and Postmarks. I have numerous reference sources to research if I do not know the answer. I am organized and promise swift courteous answers. I am a member of the American Philatelic Society. I also have my own philatelic mail order business.


As I mentioned, I have been collecting philatelic items for most of my 56 years. I have several albums of United States issues (most of them are pages I designed myself) and I also have numerous albums of postmarks sorted and researchhed by state.
