Got a couple rolls from the Jiffy store first one to come out

 

Looks like MD to Meow.

 

Mechanical doubling.. not a true Doubled Die Variety

 

Thanks figured I’d double check since I’m new at this

 

Before around 1990/91 the mint marks were punched into the dies, which already had the dates on them. When both the mint mark and the date are doubled that's a pretty sure sign the doubling was caused by a single event, the strike. Just keep it in mind.

 

That’s great information thanks I’ll keep it in mind

 

If the mint mark was punched separately and it is doubled would that mean it’s rpm

 

You got it. But remember, the diagnostics have to still be right. Take the zinc ones, for example. Those "RPMs" are plating issues, they're not real RPMs. And there could be slippage in the punch if it wasn't held steady. In an RPM, remember, you're looking for two, not one that slid or twisted a little. This is hardened steel they're punching into, so that happens. Expect they'll be adjacent and for the most part overlapping.

 

The 1960-D is both a Doubled Die (Small over Large Date ) and has a WRPM and so it is the only exception I know, and should be mentioned when making the statement . Jim

 

That’s good stuff ! Thanks for sharing the knowledge

 

Are you claiming there are no RPMs for copper plated zinc cents?

 

I was unclear. Let me try it, again. Everything before 1990/91 is susceptible to RPMs, of course. The zinc mint marks are particularly susceptible to plating issues that mimic separation and RPMs.
