Thank you for contacting Mearto with your appraisal inquiry. Based on the photographs and description provided, the subject of this appraisal is a pair of autographed Michael Jordan Rookie Style Air Jordans, dual signed by Michael Jordan. According to the current owner, the piece was acquired via inheritance. The piece features a certificate of authenticity from a defunct authenticator (Collectors Choice of Chicago Sports Memorabilia Company), and the certificate of authenticity is of the variety that could be easily duplicated via photocopy, so unfortunately the signature cannot be considered authenticated.

An SGC authenticated pair of 1990-91 style Jordans sold at Heritage Auctions in November 2018 for $1680. The Jordan market has been hot in recent months with the release of ESPN's The Last Dance documentary, so the shoes that are the subject of this appraisal would be expected to command a premium in today's market.

In consideration of the factors noted, a Fair Market Value (pre-auction estimate) of this piece conditional upon signature authentication by a reputable third party such as PSA would be estimated at $2,000 to $2,500.
