"Lady Liberty & Flag" Identifier
Look very closely at the very top red stripe of the flag. With the naked eye, you may be able to see whether it is completely red or if there is what appears to be a black dash. With a magnifying glass, you can see that it is actually microprinting that reads "USPS". Compare several stamps until you find one with the microprinting and one without. With a little bit of practice, you will be able to see this feature almost immediately once you know what you are looking for. Click on a sample below to match your stamp for whether it is the type "with" or "without" microprinting.
