Linda gave me a microscope! First photo attempt.

I can see myself now, checking for RPM, Double Dies, etc. A thanks to my wife Linda for a totally unsuspected surprise. Cool gift--here is a sample photo.

Here is a little information for you.
RPM is RePunched Mintmark.
An RPM occours when a mint employee stamps the same letter stamp more than once.
OMM is Over MintMark.
AN OMM occours when a mint employee stamps a different letter stamp over a mint mark that is already there. Like an S over a D, or an O over CC, etc.
Today the mint has placed the mintmarks on the working hubs, so these do not occour starting in the late 1990s, but before that there are many!
