Hi All! The detail on this coin is reasonably sharp, but both sides are covered by pin-prick-sized black dots, like tiny "freckles" (these are the dealer's photos, and lights may have been used, so the dots are much lighter. Photos used with permission). I don't think they are carbon spots, but perhaps this is caused by oil on the dies? Some lustre hides behind all this. A small section of the reverse rim has excess metal (seen at the bottom right as two small lighter areas), reinforcing the idea that something has gone awry in the minting process. For anyone who may know more, I invite them to share their knowledge, which I would appreciate. Thanks, AY

 

  The coin is copper-nickel, weighs 4.4g, and is 22.48 mm in diameter.

I will. Thank you, Sir. All the best, AY

Hi Sjoelund! Thanks for the tip. From the photos given previously, I can see why this occurred to you, but my coin has no bubbles, as such. I have taken two photos myself, which I believe show the problem more clearly - tiny black dots covering each side. I have chosen these two as being the best examples. I hope you or someone else can help, as I'm very curious about this. Thanks for your input and time. Cheers, AY
