Which LEGO pieces hold their value
- Retired sets, particularly licensed ones, which appreciate after they leave production
- Sealed boxes with sharp corners, which are a separate market from used sets
- Complete minifigures, which frequently carry more value than the set around them
- Original instructions and box, which add real value on collectable sets
And what pulls the price down
- Missing pieces, which buyers verify against the published parts list
- Sun-yellowed white and grey bricks, reversible on some plastics and permanent on others
- Crushed boxes on anything sold as sealed, which moves it into the used market
- Mixed-in non-LEGO bricks, which buyers treat as a warning about the whole lot
Identifying and dating yours
These are the checks that decide which end of the range a piece sits in, and they are the facts a serious buyer will ask for:
- The set number is on the box and the instructions and is what every buyer searches
- Parts lists are published for every set, so a piece count is checkable
- Minifigures have their own catalogue identifiers and are worth listing individually
WishThrift does not authenticate or inspect anything. Condition and origin are described by the seller against five grades — what each one means — so photograph the markings above rather than asserting them.

Frequently asked questions
Is used LEGO worth buying?
It depends far more on the line than the label. LEGO resale runs on the set number and on completeness, and both are countable facts rather than judgements. Each guide below says which LEGO lines hold their value for that item and which have almost none, so you are comparing like for like rather than paying for the name alone.
How do I check a piece is genuine LEGO?
The set number is on the box and the instructions and is what every buyer searches. WishThrift does not authenticate, inspect or grade anything — condition and origin are described by the seller, so ask directly and expect an answer. A seller who has the item will send a photograph of the marking in minutes.
