Key takeaways
- Sealed and retired sets can sell for well above their original price.
- Complete sets with instructions are worth far more than loose bricks.
- Bulk LEGO is commonly sold by the pound; clean, sorted, all-genuine lots get more.
- Some minifigures are worth more than the set they came in.
Sets first
Look for the set number on instructions or boxes. Search it on BrickLink's price guide or eBay sold listings for new versus used prices. Large retired sets from Star Wars (especially UCS), Creator Expert/Modular buildings, Harry Potter, and older themes can be valuable, and sealed boxes command the highest premiums.
Bulk LEGO
Mixed bricks are usually sold by weight. Remove non-LEGO pieces (Mega Bloks, K'nex), dust, and debris; pull out minifigures, rare pieces, and anything that looks special to sell separately. Clean, genuine, minifigure-free bulk sells faster at a fair per-pound price.
Minifigures
Exclusive, convention, and older licensed minifigures can sell for surprising amounts. Check each figure on BrickLink before including it in a bulk lot.
