Hello. Check out the center of the monument and the wavy shelf lines on the monument. Is this some type of error from the hubbing process or some kind of post mint damage? I'm wondering what could cause those waves. Also, this coin has some very interesting damage on the front that I will post soon. Thanks for looking!  *** Moved by Staff to a more appropriate forum. *** |

Hard to tell from the picture, but are the lines raised? Possibly struck through something when minted?

Looks like it was pressed with something. Note the columns there are flattened and probably the obverse is altered also.

Thanks all! Dave, the lines don't seem any more raised then the rest of the monument design. I believe they are about the same as the original design.

Okay...please bare with me with this still learning the die process lol.. I know this looks like a drill hit it but I thought during part of the die process, there is a cone shaped tool that is used and maybe that could have caused damage? I know this may be a stretch but just throwing it out there.

Well.. now looking... I guess there would be a point in the center of that coin too. I didn't figure it was mint.

The biggest clue that the original coin is simply PMD comes from the flattening and distortion of the columns at the center of the Memorial, those lines are scraped into the coin itself. The three metal cylinders you show are not tools used in the die making process, they are unfinished dies waiting to be hubbed. The conical tip of the die steel allows for a better transfer of the design from the hub(positive die) to the die. A hub makes many working dies so any damage to a hub would also be seen on a significant portion of the total mintage. |
