Hi Lindsey,

Thank you for contacting Mearto with your appraisal inquiry.
A chair from this group sold for just $16 at a sale in 2017 (https://www.invaluable.com/auction-lot/20th-century-chicago-bulls-chair-935-c-13a4d21875); however, there has been renewed interest in anything connected with Michael Jordan and the Bulls since the ESPN documentary "The Last Dance." More recent sales of Bulls Courtside Seats - albeit from other years - typically bring $250-350.
Based on the photos and information provided, and subject to examination, this is:

A 1998 Chicago Bulls Playoff Series Courtside Folding Chair
Black leather with Bull's logo on the seat and 1998 Playoff logo on the back; black metal tubing
number 172 of 750
with commemorative plaque
CONDITION: client represents this to be in pristine condition
PROVENANCE: given to client's father who attended the game.
$250-350*
*represents a fair-market value for auction purposes; retail or asking price may vary.
