To tell a rare Scott #594 or #596 Franklin stamp from common ones, you need precise measurements of the printed design (not the whole stamp), comparing it to known examples, checking its color for darkness (596), noting pre-cancels (Kansas City for 596), and most importantly, getting it professionally authenticated, as differences are tiny and easily misidentified. The key measurements are approximately 19¾ x 22¼ mm for #594 and 19¼ x 22½ mm for #596, but using a comparison stamp (like a #581) as a guide is often better than a ruler.
