We purchased this week a seat from the original Yankee Stadium, in existence from 1923 to 2008. Some stadium seats are extremely valuable, sometimes being worth thousands of dollars. This seat in particular is clearly made of plastic, which is a factor leading it to be less rare and valuable, especially compared to earlier seats, which were typically made of wood.
This seat is marked number 19. It was probably made in the 1980s or 1990s, upon remodeling the stadium. The certificate comes from Steiner Sports. Brandon Steiner was the original President of Steiner Sports, a brand that's well-known among Yankee fans. There are actual several unusual pieces at APR57 that were sold to us by Brandon.
