In response to determining how to label the series 1 cards:
Well i could just do the 3 digit number and the 2 letter combo after it i have -cc, -co, -sp and -no cards so far and like you stated some of the numbers also have a "b: after them but im not even sure if its possible to tget the same number with out it
BA means Bakugan
CC is Character Card, CO is Command Card, NO is Normal Card, SP is Special Ability Card
SM means Spinmaster
The B on the end normally designates the new art style. So it's VERY possible to get the same card with a B on the very end and one without. A long time ago before Bakugan ever reached the USA and the style was changed to reflect the show... the Bakugan art and names were much different than it was now for a number of characters.
The only one I've always been unsure of is the lowercase a or b found directly after the number. ( thought the a's seem to correlate to the new artwork as well.)
Examples of old Variation:

Cards BA092a-CC-SM-B (Juggernoid) and BA092-CC-SM (Juggernaut)

Cards BA026-CC-SM (Old) and BA026a-CC-SM-B (New)
