Sold Prices vs Asking Prices for LEGO

This is the single most useful hour you can spend before selling, and it is the reason most valuations come as a surprise. It is not complicated, it just needs the right filter.

Why asking prices mislead so badly

Listing something costs almost nothing. There is no penalty for asking double what a set is worth, and plenty of listings sit unsold for a year or more at prices nobody will ever pay. Search a set and you see those listings first, because they are still live. The ones that actually sold have gone.

• Optimistic sellers stay visible. Realistic sellers sell and disappear.
• A set with three live listings at 400 pounds and four completed sales at 220 is a 220 pound set.
• Some high listings are deliberate anchors that were never meant to sell.
• Search suggestions and autocomplete are driven by what people look at, not what they buy.

How to find what a set actually sold for

1. Search the set number rather than the name. It is unambiguous and it catches listings with odd titles.
2. Filter to completed or sold listings. Every major marketplace offers this and it is usually one checkbox.
3. Discard the top and bottom results. Outliers in both directions are common.
4. Look at the middle of what is left. That is your working figure.
5. Check the dates. Several sales in the last three months is solid. One sale eighteen months ago is not a price.

Read the condition, not just the number

A completed sale is only comparable if the thing sold was comparable. Before you use a figure, check whether that one was sealed, whether the box was described as damaged, and whether the price included postage. A sealed example and an opened one are different markets, and a 300 pound sale that included 15 pounds of postage is a 285 pound set.

When there is no sales history at all

Some sets simply do not change hands often, particularly older or obscure ones. That is a real answer and it matters. A set with no recent sales is harder to value and harder to sell, and an honest buyer will tell you so rather than inventing a number. We mark those lines as unpriced rather than guessing.

The gap between market value and what you are paid

Once you have a market figure, there is still a gap to any offer for the whole lot. That gap is not a trick, it pays for listing, photographing, packing, posting, storage, the sets that do not sell, and the transport to come and collect from you. What the sold-price exercise gives you is the ability to judge whether that gap is reasonable rather than guessing.

Common questions

The ones that come up once people start checking.

Why is my collection worth less than I read online?

Almost always because the figures you found were asking prices rather than completed sales. Filter to sold listings and the number usually comes down and becomes reliable.

Does a price guide site count as evidence?

It is a useful starting point, but check what it is based on. Some aggregate real sales and some aggregate listings. The completed-sales filter on a marketplace is the most direct evidence you can get.

What if one sale was much higher than the rest?

Ignore it. One buyer overpaying once is not a market price. If three or four recent sales cluster around a figure, that cluster is the price.

Should I price my own collection before asking for an offer?

It helps, and it costs you nothing but an hour. You will judge any offer far better with a rough figure of your own, and you do not need to price every set to do it.

A worked example, start to finish

Made-up numbers, real method. Say you have a set and you want to know what it is worth before anybody quotes you.

1. Search the set number. Live listings show 420, 399 and 375. That is the asking-price picture and it is the one most people stop at.
2. Filter to completed sales. Six sold in the last four months: 265, 240, 250, 310, 245, 255.
3. Discard the 310 as an outlier. The rest cluster between 240 and 265.
4. Check the descriptions. Five were sealed, one was opened, so drop the opened one from your comparison.
5. Your working figure is about 250, not 399.
