2003 S 1c - What would cause this?

[Russellhome]

Only the date and mint mark are affected. There seems to be some sort of raised outline of the date and mint mark to the southeast. The raised bumps are inside the 00 and to the lower left. They are easily seen with a 5x loop.





Is this some sort of strike or ejection doubling? Too much strike pressure? What ever it is, it is kind of different.

i may be wrong but i would say ejection damage/doubling.

I agree. With the tyoe opf material they are using for "money", anything can, and probably will happen.

Ejection doubling is when the coin, after being struck by the die, is scarped across the die as it is being ejected. This effect is seen as a ramped area, thickest at the design element affected and tappering into the field around the design element. Normal with ejection doubling, the area that is affected appears scraped which this does not have. So I would discount ejection doubling.

What this could be is ejection impact doubling, which is when the coin is ejected up into the receding die and a portion of the design is put on the already struck coin, however, even this does not seem right since the weaker design element appears to have been there first with the fully struck design transfer being applied after that.

I am not that geat with errors, which this is, however, I do know a person who is tops in the field and will alert him to these pictures. Maybe he will have an idea.

Thanks for the info. I have some old proof cents with ejection doubling - and that does not look like this. I didn't really think it was a die variety - but I thought it was pretty interesting. I just can't visualize how this would happen. The area that is raised should be flattened by the field of the die. Perhaps a heavy strike left the zink slighly molten and this is a frozen shockwave? I just dont' know.

It has an RPM look to it (i.e. those RPMs that show a faint outline of the mint mark).

I would call it strike pressure movement. On a pre-1982 cent this would not happen as I feel the plating is pushed causing the the movement of the plating. You will see this a lot on the motto on several 1990-?? forward coins.

I took a few more photos with the digital camera this time, just to see what turned up. On this one, you can clearly see evidence of multiple strikes. Not the strike damage I'm used to, but strike damage it is.
