Did they make a Mario’s Tennis Virtual Boy promotional pin? What is it worth if so?

Assuming you’re talking about this one I have pictured below? If so, then I don’t think it has anything to do with the Virtual Boy. In Mario’s Tennis for the VB both Mario and Luigi were still rocking their signature hats, but on this pin they’re wearing visors.

Hope this helps.

That would be the one. Thank you. Do you know the year it was made?
