canadian-varieties Pillar of the Community Canada 1442 Posts	Posted 11/23/2019 12:04 pm I acquired this stunning 2007 dime from SPP years back. It is black in colour, 1.6g struck on unknown foreign magnetic planchet. It has the same specifications as the black 2004 5c and 25c struck on ballcone burnishing beads (1.6g magnetic). However, it doesn't have any rust or concentric rings that are seen on the 2004 5c and 25c. Has anyone seen any other of these black 2007 dimes? Report this Post to the Staff

SPP-Ottawa Moderator Canada 10456 Posts	Posted 11/23/2019 1:42 pm That 2007 is not a ballcone. It has a completely different composition, with copper (I had XRF'd it prior to PCGS submission).

canadian-varieties Pillar of the Community Canada 1442 Posts	Posted 11/23/2019 3:25 pm 1. Any idea on what makes copper go black like this? 2. I seem to remember someone else selling a 2007 "black dime" on ebay, he/she photographed it with a dozen normal 2007 dimes surrounding it. But right now I can't find any evidence of another 2007 like this, sold at any of the major auctions. Report this Post to the Staff
SPP-Ottawa Moderator Canada 10456 Posts	Posted 11/23/2019 6:12 pm I said "with copper" - it is still mostly iron, and magnetic.

Alan Pillar of the Community Canada 1463 Posts	Posted 11/23/2019 9:08 pm It looks like it's struck on a prepared planchet, so a person would need to find a matching coin issue that they struck for another country? Report this Post to the Staff
