Build a total from the physical items you own, using comparisons that match their contents and condition. Keep purchase cost, estimated item values and possible net sale proceeds separate. Count figures included in a set only once.

There is more than one useful number for a LEGO collection: what you paid, an itemized value estimate, an offer for the whole collection and possible proceeds after selling costs. Start by identifying the physical contents and documenting condition. Brickify can help with catalogue matches, quantities, purchase records and available estimates and price history; those estimates are references rather than guaranteed sale prices.

The short version

Record exact identities, quantities, condition and completeness.
Check the dates and details behind any estimate or sale comparison.
Keep the price of a complete set separate from a scenario that removes its figures.
Record purchase costs separately from current estimates.
Treat a whole-collection offer and the sum of individual estimates as different figures.

Choose comparisons that match the item

Check the source, date, exact item and condition behind any price reference. A reported completed sale is useful when it matches the contents you own, but it does not guarantee what a future buyer will pay. Keep active asking prices, sale observations and app estimates distinguishable in your notes.

Search by set number, not set name, so you are not comparing a 2003 release against a later re issue.
Filter to completed or sold items. Active asking prices tell you what sellers hope for, not what buyers agreed to.
Read each listing's condition description and photos before you treat it as a comparable.
Investigate observations that differ sharply; exclude a comparison for a documented mismatch rather than automatically discarding the highest and lowest.
Note whether the comparable included the box, instructions and all minifigures. Those change the number meaningfully.
Subtract shipping and marketplace fees before you call a comp your expected proceeds. A heavy set can cost a lot to ship.

How much does condition affect a LEGO price?

Condition and completeness are the main levers. Two copies of the same set can sit at very different prices because one is factory sealed and one came out of a bin with three figures missing. Sort your collection into tiers first, then price each tier against comparables in the same tier.

Condition tier	What buyers look for	How to price it
Factory sealed	What buyers look forIntact seals, unbroken corners, no shelf wear or sun fading, matching regional box	How to price itCompare only against other sealed copies of the same set number and note box condition in your listing
Built, complete, clean	What buyers look forAll parts and figures present, instructions included, no discoloration or bite marks, stickers applied neatly	How to price itCompare against other built and complete copies. Mention whether the original box is included
Built, incomplete	What buyers look forWhich parts and figures are missing, whether substitutes were used, printed part condition	How to price itCompare similar incomplete contents or investigate alternative sale plans after costs.
Loose parts and bulk	What buyers look forCleanliness, colour mix, presence of printed or specialty elements, absence of non LEGO pieces	How to price itCompare similar described lots; a sample or weight alone does not establish hidden contents or a price floor.

Record whether the original box and instructions are included and their condition. Use comparisons with similar contents rather than assuming a fixed packaging premium or a faster sale. If researching separate packaging sales, do not also count that packaging in a complete-set total.

Do retired sets always go up?

No. Retirement does not establish a direction of future prices or mean all new stock has disappeared. Check actual availability, relevant sale observations and the condition of your own copy. Do not infer production volume, surviving supply or demand from age alone.

Exact identity: confirm the set number and contents.
Current availability: check actual offers instead of assuming retirement removed every new copy.
Condition: document the physical copy, packaging and completeness.
Comparison quality: note dates and whether observations match the offered contents.
Sale format: compare an intact offer with any researched part-out plan after costs.
Uncertainty: retain unanswered questions instead of converting them into a rarity claim.

Count minifigures without counting them twice

Choose what each set entry includes. If the estimate is for a complete set with figures, those same figures must not be added again as separate owned value. If you separate the figures, compare the remaining model in that incomplete state and record the figures separately.

Sort figures out of the bulk first, then check torso prints, head prints, hair or helmet pieces and accessories, because variants of the same character can differ.
Treat collectible minifigure series figures as their own category and confirm you have the correct accessories for each.
Check for print wear, cracked torsos or legs and marker or paint on faces. Figure condition is judged closely.
Price the figure, not the character. The same character can exist across several releases at very different values.
If a set is incomplete, compare the figures plus printed parts against the incomplete set comps before deciding how to sell.

Loose bricks: a worked example

Bulk is priced in aggregate. The usual approach is to establish a rate from comparable sold lots and multiply. Here is a fully hypothetical calculation with the assumptions stated, so you can substitute your own numbers.

Assumption 1: you have 54 pounds of mixed, clean, sorted loose LEGO with no minifigures included.
Assumption 2: recent completed sales for similar mixed lots in your region work out to roughly $6 per pound, before shipping.
Step 1: 54 pounds multiplied by $6 per pound equals about $324 as a gross figure for the bulk.
Step 2: subtract shipping. If the lot ships in three boxes at an assumed $25 each, that is $75 off the top.
Step 3: subtract marketplace and payment fees at whatever rate your chosen platform charges on the total order value.
Step 4: research separately removed figures only if their weight and contents were excluded from the bulk comparison. Do not assume their combined value exceeds the remainder.

A price per pound is a comparison method for a suitably described bulk lot, not a guaranteed floor. The actual offer depends on the contents, condition, sale format and available buyer. If you remove figures or selected pieces before weighing, compare the remainder with lots that exclude those same items.

A pricing workflow that scales

Separate sealed boxes, built models, incomplete builds, loose figures and bulk bricks into physical piles before you look up a single price.
Confirm the set number from the box, instructions or a verified catalogue match. Molded numbers on individual pieces generally identify parts, not the set they came from.
Catalogue what you own so you are not re identifying the same figure twice. Brickify saves items with quantities, condition and purchase details, and can identify multiple LEGO minifigures from a single photo when they are separated and well lit.
Check estimated values and price history in the app to see which items deserve a closer look.
For anything that looks significant, pull completed sales for that exact item on the marketplace you plan to sell through and write the realistic range next to it.
Photograph actual condition and completeness clearly so the comparison and listing can describe the same physical item.
Decide per item whether to sell whole, part out or keep, and keep your records updated as you go.

What Brickify does, and what it does not do

Being clear about scope saves disappointment later. Brickify is a catalogue and collection tracker with estimated values, not an authentication or appraisal service.

It does: identify and catalogue LEGO minifigures and sets, record quantities, condition and purchase details, show estimated market values and price history, and browse catalogues across LEGO, Pokemon, Magic: The Gathering, Funko, Disney Lorcana and One Piece.
It does not: authenticate an item, assign a professional grade, or guarantee a sale price. Estimates are a reference point for your own research.
For a formal valuation, for example for a high value estate or an insurance conversation, work with a qualified appraiser and bring your records with you.

Common questions about valuing LEGO

Does box condition matter? Record crushing, fading, opened seals or repairs and compare similarly described items. What about older sets? Confirm the set number or model details and look up the exact catalogue entry. A missing photo match or missing price is a reason for further research, not proof that the item has no value.

Should I seek a specialist assessment? If authenticity or a formal valuation matters, ask an appropriate specialist or insurer what assessment is needed and which service is accepted. Check scope and cost before commissioning it. Photographs and condition notes document your copy but do not replace a professional assessment.
