I was watching all of those, interested to see what they'd go for. That card has been strong at $250+ for nearly a decade. I remember buying out a store on those boxes way back in about 2003 for 10 bucks each. Didn't hit an auto but people paid around $10 for just the base set itself at the time. But, anyway, you're right on scarcity. It's very rare that even one shows up for auction once or twice a year... let alone six at once! It got my attention but I passed on adding one. You got a great card, for sure. Since no company makes well designed/auto'd music cards, that's a gem to hang on to.
Do you work for TOPPS?
Since no one answers phones, emails or customer service inquiries via the website, hit me up about that 2012 Jim Brown Five Star Autograph. Thanks!
