Is there a good place to find a list of sets along with their set symbol? I purchased several sets used and I'm not sure which ones they are. They have an AT-AT (I'm guessing Hoth), Fett's helmet, a lightsaber, and SW (which I'm guessing is the base set.

Cardgamedb is your best place for any LCG info.

AT-AT is Hoth cycle

Lightsaber is Echoes of the Force cycle

SW is the core set

and Boba Fett's helmet is Edge of Darkness deluxe expansion

Thanks for the help!
