PennyPirate New Member United States 6 Posts	Posted 06/28/2022 8:50 pm Hello everyone. I've been trolling the forum for a while and finally have found something I need help with. I recently received this coin in some change and was wondering if I may have found a new RPM. When looking through my microscope, I found that my 1970 s had a RPM but couldn't match it. The closest one I think is the 1970 s RPM-006 due to the Southern spread seen in the date and mm. The area I am finding difficult to match is the die scratches(?) in the lower swoop of the S. I've included LIBERTY in case it helps, too. Thanks for your help and happy hunting. Edited by PennyPirate 06/28/2022 8:52 pm Report this Post to the Staff

Dearborn Moderator United States 97433 Posts	Posted 06/28/2022 9:10 pm nice large date San Francisco Cent. This could be the 1970-S RPM-003 (inside the lower curve of the S) the thing at the top of the S looks like a circulation hit and was flattened out a little http://varietyvista.com/02b%20LC%20...0SRPM003.htm Forgot to ask - what is on your coin? salt? some kind of small crystal? or is that just dust?

PennyPirate New Member United States 6 Posts	Posted 06/28/2022 9:42 pm I shot it with only air between the lens and coin. I think it may be copper salts from other pennies in the drawer, maybe. I thought the greenish crystals were odd, as well. I simply took it out of my pocket and put it under the 'scope. I'll lightly brush them off next time. Thank you for the help, and I think you're right about it being the -003. I just needed to not focus on the MD matching, since that's just a loose die that can be in any direction, right?

coop Bedrock of the Community United States 62064 Posts	Posted 06/29/2022 12:14 pm Inside the lower loop of the mintmark, you can see mintmark punch damage from the punch used many times on a hardened die. This distorts the punch: Machine Doubling alters the devices on the coin. The date and the mintmark should not be showing the same direction of push by Machine Doubling. If that is seen on the coin, it is not a doubled die or a RPM. It is Machine Doubling. How can I prove that? Note this is a DDO-001 1969-S Cent. Note the yellow arrows. The arrows are pointing to Machine Doubling. we see Machine Doubling on this doubled die, but note the doubling is not seen on the mintmark? But Machine Doubling is seen on both. Why should this not look this way? The die creation is one step. If a doubled die is created on the die, by the hub, it is a doubled die. The mintmark is added in a different step. So seeing Machine Doubling both date and mintmark, this is not a RPM. But Machine Doubling. So the die was created with a hub doubling issue. Thus the term "doubled die". So when the date is normal and the mintmark is normal and showing Machine Doubling, it is not a variety, but a case of Machine Doubling on the coin. You could have both a RPM and a DDO, but the chances of the spread direction being the same would be extremely rare. (None that I know of) So when you see both areas affected the same, it is Machine Doubling on those areas. CoopHome: What does it mean, if you see what look like doubling on both the date and the mintmark? ( Machine Doubling) Report this Post to the Staff
coop Bedrock of the Community United States 62064 Posts	Posted 06/29/2022 12:16 pm Also the OP's coin is also showing extreme die wear. Looks like the dies were polished many times and not the devices are getting smaller and smaller after each polishing. This coin is just a spender. Report this Post to the Staff
