52 pieces, zero minifigs, and a price tag that treats you like a tourist — the AT-M6 polybag is a D and it's not a close call.
The parts alone are worth about 80% of the street price — the basis for this D+ price read.
FairParts are worth about 80% of the price — close to what the set is worth.
The AT-M6 is one of the more intimidating walkers in the sequel trilogy, so it's a shame this polybag version squanders the license almost completely. Fifty-two pieces can't do the beast justice — the proportions are off, the legs look spindly, and there's nothing to anchor it as a display piece or a play piece. No minifig means no pilot, no rebel, no reason to stage a scene. The price grade is a D, which says everything about where LEGO® set this one relative to what you actually get. Polybags live or die by charm, and this one doesn't have enough of it to justify the ask. Skip it unless you're completing a collection and even then, wait for a markdown.
