I'm no stranger to coins, and I've seen my fair share of weird stuff, but I would appreciate any insight as to what this may be:
It's a 1968D cent, weighs 3.1g, but is uniformly grey in color! Now, before you say "electroplated," I've performed a scratch on the edges and the metal underneath is this same grey color, albeit shiny. It's not misshapen or a wrong planchet, it actually is a very nice cent. Why is it this weird metal???? Offers!!
