I think it bears a lot of similarities with the experimental example on the Wiki page, but I really don't know anything about coins.

The one pictured on the Wiki page is the aluminum one I posted a pic of. Does yours feel light for an old penny? The old(70s and earlier copper pennies weighed more than the new early 80s until now pennies. If steel yours should feel about the same weight as a newer penny.
Have you tried to clean it with anything or is that the way you found it?
