Yes. Many valuebal errors come from useing the still good last years dies. They change the date ( and or mm) but do a sloppy job. Thats why we have things like repunched mint marks ( RPM) and over date and mint marks. If you want to learn more about any mint error learn about the minting process.
The basic way to give a general error type is to use the P,D,S, system. It stands for Planchet, Die, and Strike. If it is a RPM or like coin it is cald a varity ( a die varity).
As you can see I like error coins.
