The first one is from Spring Training 1983, due to the presence of Roy Smalley and Steve Kemp (both of whom were gone from the team by mid-season 1983) Billy Marting managed the oakland As during the 1982 season then quit/was fired/was asked to leave after blowing out the A's Pitching rotation during said 1982 season (the same rotation he used to lead the A's to the playoffs in the previous 1981 season.) 1982 was also the year Rickey Henderson set the single season Stolen base record while under Martin.

Bornyo needs to provide more info about the card in general, beyond the copy he has posted. If it were just a plain piece of papaer/cardboard with all those signatures, if you get it authenticated (a must if you want to get top dollar for it) It is worth a minimum of 400 bucks primarily due to Martin's signature. Why his autograph is worth so much more is simply the predilection of collectors and memoribilia freaks who buy this stuff, plus the fact that billy martin is dead and thus a rarer signature all around (like any commodity, his autograph will obviously no longer be available so the SUPPLY of it is now fixed and dwindling...everyone else is still alive)
