Hey Everyone, I've been a long time lurker here and have always appreciated the insight from this community. I ran into an error that I was hoping to get some input on. It's a 2010 P Sacagawea. The error almost looks like feeder finger scrapes but I've never seen this much damage from that type of error. Any ideas would be greatly appreciated!    Edited by CRHunting

That is a creepy looking dollar. Idk if that from harsh polishing or what exactly, I'll wait to here what others say on this one. Edit:if possible can you post a picture with less lighting? There is a lot of glare but definitely something going on I think. I don't think it would be Feeder Finger Damage as this would be a low point on the die. Edited by Wrekkdd

Thanks for looking Wrekkdd. I agree with your thoughts on Feeder Finger Damage. I've included a picture with less light. I'm still trying to get a hang of taking these close up shots. Let me know if any other images would be helpful. Thanks again!  |

This reminds me ALOT of the bare belly 1990 Canadian 5cent. It still does not have an 100% lable yet from what I have read. I'd love to know exactly what causes this. This in particular is more of a low point on the die then the beavers belly so I would love to hear what the experts think.

the anomaly extends to under the chin. that area would be the high spot on the die so I 'm thinking die scratches or a gouge?

 Didn't see under the chin there, it still is a bit weird, the fields under the chin seem less effected then the low parts on the die, I'm still curious about this one. It's very cool looking IMO but also a little creepy looking. What ever it's chalked up to I'm gonna think this is the same event that occured on the bare belly 1990 5cent(or at least part of the same error) |

I need to see more of the area just right of the cheek on the right side of the image that is almost off screen. it looks like it continues there too. (the area identified by the red arrow).  |

Dearborn will these work? I can take other pictures if there's too much glare.   |

Feeder Finger Damage to the die. The "low" spots on the coin correspond to "high" spots on the die since it's essentially a negative of the coin,(quotes used since low and high are relative terms here), and since the feeder fingers contact the highest points (or most raised) on the die first, you expect to find them on the lowest points of the coin, such as the fields and low spots on devices.

Isn't the feeder finger solid or is it flexible, for it to effect the devices on the coin as well as the fields then it would have to bend, or be tilted on an angle causing it the scrape the portrait(incuse on the die) and then also scrape the fields only a tiny bit. The most effected part is the design, so I'm not quite sure how a feeder finger would do this to the design but then barely effect the fields which would be the highest point on the die
Edit:maybe I have my terminology backwards, but the fields are the least incuse part of the die and the devices and portrait at the less incuse parts of the working hub, I realize I was saying die, sorry. I thought the feeder finger had to do with the production of the coin, not the production. Of the working hubb?

To sum up, I'm not sure the feeder finger would effect the low points of the working hub this much, but then have little effect to the higher points of the working hub.

Looks like a clash from the ribbon on reverse, Need an overlay.

A clash would be raised above the portrait, also a bit of a strange spot to have a clash when it barely shows on the fields. Even though the raised lines are obvious but they still seem to be below the area effected on the coin. I don't think this could be caused by a clash. Edit: if you have never looked at the 1990 bare belly beaver I recommend checking it out. It has the same sort of pattern with raised lines as this. I would have to go check the article in the CN journal, but I don't know that it ever concluded 100% what caused the error. I know nothing about us dollars but have a really good handle on the minting process(even though I can mix up terminology). I don't think it's Feeder Finger Damage but I'm fairly positive a clash would not have this effect. Edited by Wrekkdd

The feeder finger moves the planchet into the striking chamber (feeds it) and then ejects it from the striking chamber. If a die comes in contact with the feeder finger the result is usually a scrape or series of parallel scrapes across the die, affecting the highest point of the die. This is because the feeder finger is flat, but the die is not, so the flat surface of the finger hits the most raised parts of the die. Usually, this results in scrapes or lines showing up on the fields only, because the fields of a coin are the highest point (generally) on the die. But those scrapes are not limited to just the fields. They affect the die based on height, so if part of a device is as low as a field (on the coin) then it stands just as much a chance of being affected as the field. Look at the areas affected on the OP's coin and you'll see they are actually lower than the immediately surrounding areas. The area in her neck affected are the parts that are lowest, in between folds as it were. Likewise, the gap between the baby's head and her neck is a low point on the device with the surface clearly going from high (baby's forehead) to low (gap between baby's head and her neck). Additionally, on the Sac Dollar Coin Feeder Finger Damage generally run in this direction, from NE to SW based on other examples. Admittedly, it's unusual to see it like this, but not unheard of. I think it's a cool enough coin to keep. |
