In case anyone unfamiliar with that case is curious as to how it turned out:

Baseball Card In Dispute Will Be Put Up For Sale
April 23, 1991
WHEATON, ILL. — A baseball card that has been the focus of a court battle between a schoolboy and a dealer will be sold 
and the proceeds will go to charity, the two sides said Monday. Brian Wrzesinski, 13, of Addison, and baseball card store 
owner Joe Irmen announced their out-of-court settlement Monday minutes before a judge was to rule. Wrzesinski bought 
the Nolan Ryan rookie card last year for $12. Irmen sued, saying the card marked ''1200'' was worth $1,200.

RYAN ROOKIE CARD SELLS FOR $5,000
Saturday, June 22 1991 12:00 a.m. MDT
Bidding for a controversial Nolan Ryan rookie baseball card started at $12 Friday, and within minutes the card sold for $5,000.
The auction was held following a settlement between 13-year-old Bryan Wrzesinski, Addison, Ill., and baseball card store 
owner Joe Irmen. On April 24, 1990, Bryan bought the card for $12 when a clerk in Irmen's store did not realize the price tag 
actually meant $1,200. During Friday's sale at Chicago Riverfront Antique Mart and Auction Co., Bryan Wrzesinski symbolically 
began the bidding at $12, but the next bid was $1,200, by Joe Irmen, the other figure in the controversy.
The bidding rose steadily until the card was purchased for $5,000 by Tony Del Angel, 39, of Lisle, Ill. "I look at it 
as an investment. Within a few years, I'm going to get my money back," Del Angel said. 
Fascinating discussion of the legalistic implications of the case here:

It'd be a hoot to argue this over beers with the contract lawyers on board...
