I have the same question as pyrbob. What is the diameter of the coin? Is it the same? If so, have you actually taken a pair of calipers and measured something on each to compare sizes? Maybe the "C" in cent. See if they are in fact the same height? If the diameter is actually larger, all bets are off, and the experts will have to chime in.
If the diameter is the same, my guess is optical illusion with the color differences making something appear larger. Maybe it's much easier to see in hand, but when I concentrate on just one letter compared to the shiny cent, I have a hard time actually seeing a difference in size. Maybe it's the fact that the gray coin is more worn, or in essence flattened out a bit and is making it look larger due to not having as much depth perception.
Maybe it was heated and run through some kind of press....
