A quick heads up if you are attempting to discern the VALUE difference between #654 and #655. Both stamps are worth less than 50¢ used and unused no more than a couple of dollars. Therefore you might not consider the identification process below useful to you.
STEP 1 - LOCATE A USED ROTARY PRESS STAMP OF THE SAME SIZE
A great choice would be any of the lower stamp denominations from the 1938 president series shown above . The used stamps have negligible value, less that an nickel, so not much harm done by cutting them up. However I would not use the dollar values of this series as they do have some value.
STEP 2 - CUT THE CORNERS OF YOUR CHOSEN STAMP
Cut a square out of each corner as shown above, make sure you cut into the design. I chose a used one cent stamp, but any used lower denomination from the 1938 series would do.
STEP 3 - PLACE THE CUT STAMP OVER THE EDISON STAMP
Once you have followed the visual guide above, click the image above that most resembles your Edison stamp.
