USA - Microprinting - Stamps on Cover
Note: On US definitive (regular) issues, only some varieties have microprinting incorporated into the design. Not all printers of these stamps used this feature consistently when printing reprints. The varieties of stamps of these basic designs that have microprinting are in the great minority. Out of 300 random covers with regular, definitive stamps affixed that were searched in December 2009 to find the items pictured below, only 8 had varieties affixed that had the microprinting. In other words, these are not very common.
Commemorative stamps that have microprinting were usually printed by only one printer among many that that the US Postal Services could put under contract. Commemoratives are generally printed all at one time from one plate and are not reprinted. So, if microprinting was used on a commemorative stamp, then usually, all of them wll have the micro-sized lettering.
