I don't know if this is a double die or Machine Doubling. I see there is a clear separation on the doubled parts of the numbers and both parts are raised. There not flat like most MD I have seen. Need advice from better minds on this one.

appears to be a classic case of machine doubling--flat/shelf/plateau-like.

MD. Note that a DDO would not affect the mint mark on a coin produced in 1989 or earlier, since the mint mark was punched by hand in a process separate from the hubbing.

This one could be an example of master die doubling. (50% of the cents that year had that issue)

But not a doubled die that is collectable. The first clue it is not a doubled die, is that the date and mintmark both show the same thing. The die is created in one process, the mintmark is added in a different process. When the MD affects both, that is the clue for Machine Doubling. (as well as the outside edges of devices are affected)
