It is a 1922 series stamp. There are many varieties of the 1c Benjamin Franklin stamp. Do you know how to measure the perfs? If so, that will help narrow it down.
ggreve provides the starting point - an accurate determination of the rate of perforation - NOT a measurement of the image size. In this case, you will find the top/bottom are perf 11, the sides are perf 10.5, which equates to 632.
The identifier on the stampsmarter site does a poor job with booklet identification details, like 552a and 632a. Your stamp is perforated on all 4 sides and must come from a sheet. The booklet panes of 6 have a cut edge around the perimeter, thus any single stamp will have at least 1 straight edge.
