On RPMs as well as doubled dies, some notching is seen between punchings/hubbings depending on the spread of the hubbings/punchings. Here is an example of RPMs that helps you to see what the direction of RPMs are. But not the last line. On these the splits on the serifs appear on the mint marks.  I don't see this on your example.

No one commented on my 1989-D RPM pictured in this thread. When first posted at Lincoln Cent forum,lots of people said it was Machine Doubling,plating issue....etc.... Charles Daughtrey saw the picture and said: "Theres no doubt at all,Thats an RPM and a nice one! Those are scarce!" |

ok,, I found this definition on CC for notching "All I mean by "notching" is places where the design is separated.
In other words, it shows two independent processes, versus MD."
but if the "spread" isn't very wide then it may not have "notching"? anyways. if the date is in no way doubled how can the mint mark be MD? I'm so lost....is this all very subjective from one opinion to another, or what... I would love a quick bullet point your coin is RPM if: it does have _____ and does not have ____ is there a sight with this info?

This is all part of the collecting game. Sometimes you just have to send the coin in to be attributed. I send coins in all the time to different attributors such as: CONECA, John Wexler and Bob Piazza at Coppercoins. I have had many coins over the years that had to be sent in to get a final answer. If I had that coin,I would send it in. Also:Just because you dont see an exact match listed anywhere does not mean ANYTHING.You coin may be a new listing. Happens all the time and I have dozens of "discovery" coins,from pennies to Half Dollars. Just 2 weeks ago I had a Franklin half "Bugs Bunny" attributed as a new die (#3) There were only 2 dies known before I submitted the coin.....so ANY coin possibly could be an entirely NEW listing. After looking at your pictures again...I think I see a split in the tail of the first "9" and extra thickness on the right side of the "8" and its maybe possible that the coin is also a minor DDO.

Risky? Only if you dont think the US Mail can get it delivered.
It costs anywhere from $3.00 to $5.00 per coin to get it attributed plus return postage.
It can take a couple of weeks round trip...no big deal.

Joey - yeah I just don't see the cost effectiveness in it to send in a penny for $5.00 just to have someone give their opinion if there are no set rules for what something is, it seems rather subjective. I was really just hoping to know for sure what it was so when I listed it I could name is for sure what it was, and not get bad feedback. maybe I'll just start listing interesting pennies as just that then I can't get dinged for calling it something its not and people can just make their own decisions. Joey, thanks for your help I really do appreciate it. you've been very supportive.

so. I guess if anyone was interested in this coin I had cancelled my listing before as it was called an RPM. I am gunna just list it as an interesting 1985 D and see what it does. I'd had several bids already but it was not worth the bad feedback to not be 100% sure what it was.

Mint marks are punched into the dies on pre 1990 coins. When the mint mark is too deep, it become taller than the other devices (date digits). During ejection this may hit part of the die, thus damaging the mint mark. On your coin moving it from the original position. RPMs are usuall enlarged somewhat larger in size in various directions. here are a few examples:  Note how the RPMs are larger than normal or have splits on the serifs as in the case of tilted examples? Yours just looks like pushed metal ( Machine Doubling). |

coop thank you that is a great illustration of marks.....how is mine much different than the N on the second to the last line? mine I think is NW but still looks a lot like that N... besides inspecting the mint mark, you had asked about the date. my date is not doubled nor is any other part of the penny. is that not relevant because of the year? at this point I feel like I'm being stubborn. but I really want to understand in general how this is not an RPM I've got tons of pennies that I know are MD and a few I know are RPM they are "on the list" and some you have been very helpful to teach me about other errors. and I've been learning a lot I really am appreciative.

wow, thank you, that first one of the 83 is the closest one I've seen to what wee have. I'm ready to concede the point. but could you point out the differences between that and http://koinpro.tripod.com/Varieties...1cRPM001.jpg which is ken potters RPM I feel like I'm looking at one of those kids puzzles to find the difference and while obviously its going in a different direction but what am I missing...? |

http://www.coppercoins.com/lincoln/...ie_state=mdsThat one is RPM # 1 1985D-1MM-001 on coppercoins. It is a south east. D/D Notice how the mint mark is strong and the RPM is weaker. On your coin the mint mark is damaged from ejection doubling/die movement. The machine normally strikes normal coins with these dies, but then a problem with the machine damaging the coin you received. On a RPM all coins struck with that obverse die has the same location for the mint mark and exactly the same direction & spread. Because of die wear the shape may change a little from different die states. Here is an example of one:  Highlight message to the right...... They are both from the same die. Just different die states. Note the die scratches on both coins. The one is fading, but they match up just like finger prints.

Hi Mary,
If Charles Daughtrey said it is an RPM, why are you still questioning it? He is an expert and he works with Bob at CopperCoins.com. I think Charles has another site too.
