Examples of Plate Number Singles

Our goal is to illustrate one example of a plate number single for every U.S. stamp that was issued with plate numbers.


We also illustrate plate number singles on proofs, trial colors, specimens, errors, freaks such as misperforations and color mis-registrations, precancels and other varieties.
