I thought it looked close to 1mm-011. I am unsure though.  |

Without a side by side, I think it is 011. Either way - nice find.  Edited by CoinMasters

Looks a bit like the CONECA 1971-D RPM-004?  |

An overlay with 1971-D 1MM-011 looks like a match, can you find any markers?

The rpm is the extra metal on the left side of the D right? It wouldn't be the light shadow below and to the right of the D. Just wanted to know for clarification on rpms. Thanks.

On an RPM, MS7OE, one looks for a previously punched mintmark (or a remnant there of) underneath or near the primary mintmark. All RPM's are on coins minted prior to 1990, because at that time, they were hand-punched on the dies with a hammer. Sometimes they didn't get it right the first or even second time and "polished" off previous punchings before re-punching, however, they sometimes missed some of it. That's what we look for.

It would be impossible to polish off a mint mark. They are the same height/some taller as the other devices on the coin. They just leave the arrant punch or discard the die.

Oh ok. Thanks for the information. I thought a machine punched the mintmark separately. I didn't know they were hand punched.

Thanks for correcting me Coop. Of course you're right. Sometimes I wonder what I was thinking. It would certainly be hard to polish off something incuse on the die (air). Were the old punches diamond tipped maybe?  |
