Stamps (Philately)/A155


Good Evening! I have a stamp collection that was my Grandmothers that I am just started going through. I found a set of two stamps that do not look used just aged needless to say. Really nice deep green, looks like from the A155 Ben Franklin series. I would like to know how to find out which one it is.

Thank you so much for your help!


The stamps look to me to be Scott 552, the 1923 flat plate issue perforated 11 x 11.  I cannot be certain without direct examination, but the perforations, color and proportions seem consistent with those of Scott 552.
