This coin appears to have an RPD but I need opinions. VarietyPlus and CoinFacts assign a DDO FS-101 designation to this  Edited by mdpmedia

This coin also appears to exhibit Longacre doubling but I need some advice as to whether or not that would negate the the existence of a DDO? That is because the aforementioned DDO FS-101 3CN is grouped in with an RPD under that numerical description. Another thing that confuses me is that some of the doubling looks like it's doubled or even tripled. SO, what type of variety is this?  |

Is it possible to have a combination of a flattened Longacre showing on both sides of the U, for example, along with tripled Machine Doubling present elsewhere? |

Since Longacre is caused by the punch itself it seems like it's theoretically possible to also have hub doubling or Machine Doubling. And if the date was punched into individual dies (I don't know if that's true for 1870 3c) certainly a DDO and RPD could both occur on the same FS-101 designation. Correct me if I'm wrong, of course. |

They are neat coins. Need to have a good reference for the errors though.

More of an issue with die wear, Machine Doubling and what appears as a RPD or a die crack. But It looks for follow the '70' more. (perhaps a first punching issue, the rest of the date looks like it is above that area. Machine Doubling can be seen on a normal coin or a variety as the MD is part of the striking setup. On die wear it is an issue with die showing die wear. A RPD is an issue with the die creation. So all three can happen during the different steps. The DDD is more of a modern issue on the single squeeze dies. On the DDD, only the fields are affected when the lower profile devices used. Thus the term I prefer on the older die creations is die wear. The big difference on the two is that the devices are alter on die wear, where as on the DDD the fields are affected. Both are die wear. Both are slightly different. Hope this helps. |

https://periodictable.com/Propertie...ness.al.htmlI'm assuming that the Die Deterioration shown In my example is typically more prevalent with nickel compared to copper because nickel's 33% higher Mohs value causes a die to wear out more rapidly? I make that assumption after reading the verbiage written within the JPEG below found in the thread that coop referred to previously:

I just checked my CPG and the PUP's are there...looks like a winner! "Secondary digits are evident to the west of all four primary numbers." To the left of the flag of the "1". Between the "8" and "7" is the flag of the "7". Inside the opening of the "0".  Cross Reference Fivaz-Stanton (OLD): FS-005 Flynn-Fletcher: DDO-001 & RPD-001 VarietyPlus: VP-001 Diagnostics The date was boldly repunched to the northeast of the first impression. Minor doubling of the obverse is also present. https://www.NGCcoin.com/variety-plu...1889/815903/Edited by oih82w8

The photography of the NGC example even shows a faint vestige of that odd downward-pointing, right-curved hook-like appendage hanging off the far left base of the '1'.
My example of this same feature is much more predominant. I wonder what that actually is since it's hard to imagine that it's part of a re-punched '1'. Any ideas?

Just in case anyone would like to see a much better representation of the complete obv. & rev. for PUPs ID, here it is: I had lighting and unknown post-processing issues during the first shot I posted earlier:  |
