This collectible is pre-owned and in good condition. The Regional Semifinal is the Sweet 16.

These pins were used by players and coaches as their credential for event. 

These pins are extremely rare and limited, and I have an entire collection going all the way to the National Championship Game in my listings, so be sure to check them out.

Based upon the lot of pins I bought these in, this was formerly a Michigan State University player or coach's pin.
