Quick value checklist

Find the set number on the box, manual, inventory, or online part list.
Separate sealed boxes, complete boxed sets, incomplete builds, loose parts, and mixed bulk bricks.
Photograph minifigures, instructions, boxes, seals, sticker sheets, rare parts, and yellowed or damaged bricks.

Key value drivers

Set number is the starting point. Sealed retired sets, complete boxed sets, rare minifigures, strong themes, clean instructions, and original boxes usually matter most. Loose mixed bricks can still be useful, but they rarely compare to complete or sealed sets unless rare parts are present.

Condition and originality cautions

Auction records do not prove the value of your set. Missing pieces, replacement parts, opened seals, brittle or yellowed bricks, box damage, incomplete minifigures, and mixed inventories can materially change value.

Photo checklist

Box front, box sides, set number, seals, instruction covers, inventory pages, minifigures, sticker sheets, rare parts, and full contents.
Close-ups of broken hinges, yellowed bricks, cracked minifigures, missing accessories, tape, crushed box corners, and water damage.
