Kay,

A quick signal for me on auction sites is that edition numbers for limited editions are numbered as 10X, 20X, and 30X; GLOW edition numbers start with 40X; Collectors Society pieces are numbered as 50X; Special editions and Event Pieces are numbered 60X, Christmas editions are 70X; Little Lights are prefaced by LL. I've seen a number of auctions of Little Lights where the seller lists it as an HL piece, but the size (if given) and/or the opening bid (usually) tells me it's a Little Light.
