I recently obtained a 50th Anniversary Eames Molded Plywood Lounge Chair. In reading the card that came with the chair, I know it is 1 of 500 that were made in 1996 out of Herman Miller's last remaining rosewood stock. I believe that the chair retailed for $1,400, but I'm trying to figure out its value today. Anyone's help as to how I determine it's value would be much appreciated.
