NHL San Jose Sharks Hat, EXTREMELY RARE! Vintage, solid black w/teal piping, NWT

Cleaning out my dad's closet and I found this extremely rare San Jose Sharks hat. It's solid black with teal piping, teal covered rivets and teal top button. I looked all over the internet and couldn't find another one like it. It's never been worn. New without tags. Wool with acrylic.
