Here's what I believe is an RPM titled and could only find 1973D-1MM-001 as the closest reference.

Can't tell with this one due to the hit it took on the MM. You could check it for the markers listed with the 1973D 1MM-001. But wiht the damage I don't believe there would be any premium to this one.

That looks like a Mintmark that took a hit, making it look like an RPM. However, the mintmark is in the right location. Check out the other die markers, but I wouldn't get my hopes up.
