I was just having a hard time finding out about a few Nintendo controller cover variations that I have seen over the years.

The two that come to mind if I can remember is there was a happy birthday Nintendo controller with a 1993 I believe and the 9's were put under the A and B buttons.

The other was a white spiky haired boy right in the center. His sunglasses were the start and select buttons.

I was just wondering if there was any more besides that, and how valuable they really are.
