-makecents- Pillar of the Community United States 8784 Posts	Posted 09/17/2025 6:38 pm Pete, not sure if this may be Feeder Finger Damage but hoping the OP will take a closeup of that area I have circled. LINK https://goccf.com/t/483648#4357955 -makecents- Report this Post to the Staff
NY Islander Pillar of the Community United States 981 Posts	Posted 09/21/2025 12:42 pm Hi Pete, Came across this 1958 D today. It's definitely a RPM. Probably the 1958 D-012. The damage near the bottom of the bust is similar to that of the 1959 LWC I posted on 6/20/25. The damage is listed a die gouges on VV. I'm not sure if this does, or does not support your belief regarding finger feeder damage. Either way it is more information for your research.

Dough101 Valued Member United States 399 Posts	Posted 09/21/2025 4:43 pm Many coin experts have informed me that this type of anomaly is known as "roller marks/planchet irritation". Thank you for this information. How about this? Report this Post to the Staff
Pete2226 Pillar of the Community United States 3331 Posts	Posted 09/21/2025 4:57 pm Dough101 That is plating irregularities = corrugation. I think I have posted a paper about that in the group. Using my phone now, but will search for that link tomorrow when I return to my computer. If you find it before then, let me know. Report this Post to the Staff

Dough101 Valued Member United States 399 Posts	Posted 09/22/2025 10:36 am Good information: a lot better than just saying planchet issue, Dryer Coin, etc. Thank you. Report this Post to the Staff
Dough101 Valued Member United States 399 Posts	Posted 09/22/2025 11:45 am @Pete, Has any research been done on " Machine Doubling" and "Hub Doubling"? I am not sure if these two anomalies are both mint errors or something else. Are these two tools used by the mint, etc? I see lots of coins that are claimed to be double dies but look like a reflection/splash. Need facts. Thank you. Report this Post to the Staff
CoinHI Pillar of the Community United States 2736 Posts	Posted 09/22/2025 12:10 pm I might have another 57D example for you Pete. I have multiple examples all showing the same scrapes. https://goccf.com/t/483763 "Pride is yoked with callous behavior, as humility is with compassion."

Pete2226 Pillar of the Community United States 3331 Posts	Posted 09/22/2025 12:29 pm CoinHi Thanks! Very Interesting! I am adding it to my census! There are so few examples of 57D and this is first I have seen for the Reverse! Report this Post to the Staff
CoinHI Pillar of the Community United States 2736 Posts	Posted 09/22/2025 2:51 pm Great Pete! so you'd say this is feeder scrapes for sure? I can send you one to keep and study if you like, lmk.

Brandmeister Pillar of the Community United States 6554 Posts	Posted 10/06/2025 3:44 pm Two nickels that I recently found. No conclusions yet as to whether the coins show Feeder Finger Damage, trail dies, or some other form of long, parallel die scrapes or gouges. https://goccf.com/t/484216 https://goccf.com/t/484215 Report this Post to the Staff
