can you get a better (closer) close-up of this? Maybe with the light source coning in from a slight angle.

Quote:I haven't found one of these myself yet, but having just scoured error-ref for something else, I have this at hand: https://www.error-ref.com/die-rings...and-spirals/ Thanks for this - never saw it before. I am not sure this is the same because this one is not at the center of the coin. I have no idea what causes the rings and spirals in the article you reference but it looks like rotational ridges caused by machining. |

Has it passed the acetone test?
Inordinately fascinated by bits of metal with strange markings and figures
