Hello,

I am new to this site, and to stamp collecting in general, and I am stumped on a few stamps I have. I have a couple "green one cent franklin stamps from the 1922-1931 era, I think.. anyways, I have perforated these stamps, and they seem to be a perf 11, however, they do not seem to be the flat plate perfed 11 stamps. The design to me seems bigger than the ones printed on the flat plates. How would I find out, or know if this was a rotary printing, and if the perfs were genuine. Thanks in advance for any help you can give.
Don

Welcome to the forum, djohnson702!



The rotary press stamps are a hair larger than the flat plate press stamps. You really need one of each side-by-side to tell the difference. The US Stamp Identifier at the front of the Scott US Specialized catalog can help you identify the Washington-Franklins. It is a challenging series.

I ran across this old topic while trying to research color on 737 vs 738. My Scott Specialized says 737 and 738 are both purple, while 754 (the imperf version) is deep purple. My 737 matches the picture in the Specialized as regards color, but my 738 is a MUCH deeper purple. However, the 738 is definitely perf 11. Has anybody run across this before?

Thanks,

Alan
