Since I didn't find any particular meaning neither for AGBG nor for AEJB then I'd have to say that in the resellers market they could currently go this way:
AGBG.info about reg fee
AEJB.net about $10 (since it is a VVCC)
I know they are both LLLL domains, I know that the .info is a quad premium, but, just taking a look at marketplaces you'd easily notice that "generic" Quad-Premium.info and Triple-Premium.net (even VVCC) are going for these prices.
Anyway I'd keep them, if you can (the .net in particular): they must increase their value as time goes on
