Chris,
Steve is right and here is a link to the cubanball.com site (GREAT SITE!!!) that talks about them...As for value- I got one that was cut (all I got was the two sides front and back) and paid $20 I think...And if I'm not mistaking I saw that at the Nation and the deal wanted somewhere around $35-$40...
