I think I've seen something similar posted but don't recall if this is related to a reduction lathe mark or something. Anyway, it's light, perhaps better in hand. Let me know what you think it might be. Thanks!  |

Yes, there have been a couple of these posted. I do not think a definitive answer has been give. I have not found one yet. I would love to find one, and really would like to know WHAT THE HECK it is. Try PMing Mike Diamond. I would assume it is an error of some sort.

These tiny, raised, centrally-located circles have been observed on the reverse face of Lincoln cents minted around the turn of the millennium. Sometimes they take the form of a complete circle. In other cases they form facing semi-circles. Unfortunately, there hasn't been any progress in determining their cause. Some have suggested they're related to concentric lathe marks, but I doubt it, as they're never accompanied by outlying circles.
Yours is the first I've seen on a nickel.

Thank you Mike. First I've seen too. It kind of looks like an ejection pin mark commonly found on molded plastic parts. This one is fully concentric.

Well, if it has Mike Diamond stumped, it must be crop circles.

Actually, these tiny, centrally-located circles and semicircles appear on 2004 cents. Here are two examples:   Error coin writer and researcher.

That last cent pictured makes it look like President Lincoln is sitting in No. 2's chair from the 1960's "The Prisoner" series with Patrick McGewan:   spelling error corrected How much squash could a Sasquatch squash if a Sasquatch would squash squash?

I never saw that before.  Looks like something very small and cylindrical came in hard contact with the die. Maybe a piece of equipment or a tool. Mike's second pic makes me think that it can unravel or is adjustable. Unfortunately I remain under-educated in the minting processes. |

Holy crow these are crazy! CM I was thinking along the same lines-something hard is falling on the die and damaging them when they press the coins but they are all centrally located so it cant just be something falling on the dies by chance  do you think this is happening somehow during the time the working hubs are making the working dies? Just seems too coincidental for the dies getting damaged somehow during minting process when its so centrally located on all these coins? Edited by Slamnbass
