Why does my coin look so different from NGC?

Do I have a fake?

Mine looks old and crusty and says 1675 2 M on it. NGC Looks like this:

This isn't the first time NGC's site has the wrong picture - they get all coin specs and pictures from Krause, with all of Krause's errors. NGC does fix them a lot faster, though, if you let them know about it.
