You are bidding on a Nintendo Super Mario Bros. Coin Pinback Button.  The button measures 1.375" (3.5 cm) in diameter.  The button is in great condition.  Please see all pictures. 

The button will be packaged well with shipping within the United States through USPS.  Shipping out of the United States only with eBay's Global Shipping Program so additional fees may apply.  Please check out my other auction items.  Contact me with any questions.  

Thanks for looking.
