This is the ONLY known classic metal Super Sonic pin. It's a silvertone metal & enamel pin. It uses one of the few classic arts of actual Super Sonic, & as you can see here was actually (interestingly enough) made by Sony Products, but produced for Sega. Note the "Segasonic" header on its plastic card. In 2013, someone tried to sell it on ebay for 541 dollars, but FAILED when they wanted even MORE money for it than was offered! It's an outrageously pricey pin.
