peter chaoBarry's pretty accurate. Once in a while a case concerning baseball cards or memorabilia will get into Small Claims Court here in the Bay Area. However, if an attorney brought an action in the Superior Court the action would be laughed out of Court by the Judge.
One notable exception in recent memory was the furor over Barry Bond's home run ball. However, at the time people thought the ball might be worth a million. I knew one of the attorneys involved in the litigation and asked him about it. He said the Court took the case seriously only because of the value of the ball and the publicity surrounding it.
Good luck on your presentation.
