James,
*1990 have variants (different colour writing for the team name in either black or blue) for the following teams logos
Canberra #1, Bulldogs #30,Sharks #39, Bears #94
*1992 Has error card Langford #50 and Harragon #71 where their stats on the back have been switched. The correct ones seem to be the rarer
P.S. I need #64 if you have 1 spare
*1994 has gold cards and gold signature cards which are more valuable. As is the Hometown Heroes and Dynamic Duos cards
*1995 has Force 5 signature cards and cheap inserts such as Men of Steel and Front line Enforcers
*1996 signature cards again are worth a bit but the original folders even more
*1997 have the meltdown cards which you can get up to $5 for
Hope that helps
