We compared returns from 2,123 retired LEGO sets against the S&P 500 and gold. The results? LEGO's average 75% appreciation crushes traditional investments — and some sets returned over 8,000%.

Can colorful plastic bricks really outperform Wall Street? We ran the numbers on 2,123 retired LEGO sets and compared them head-to-head with the S&P 500 and gold. The results are striking — and they might change how you think about alternative investments.

The Headline Numbers

Asset ClassAvg. Annual Return10-Year Total ReturnBest Single Asset Return
LEGO (Retired Sets)~11-12%75% avg. appreciation8,020% (21038 Las Vegas)
S&P 500~10.5%~170% (2015-2025)Varies by year
Gold~8-9%~120% (2015-2025)Single-year +25% (2020)
US Treasury Bonds~4-5%~50%Limited upside

The verdict: LEGO's average appreciation of 75% across all retired sets is competitive with — and in many cases superior to — traditional investment vehicles. And the outliers? Nothing in stocks or gold comes close to an 8,020% return.

Year-by-Year LEGO Performance

Here's how sets from each release year have performed after retirement:

Release YearSets TrackedAvg. AppreciationAvg. Profit Per Set
2018310153.0%$56.46
201930399.3%$38.81
202028177.1%$39.88
202129951.3%$25.73
202229246.5%$23.82

Key insight: 2018-era sets are the clear standout, averaging a remarkable 153% return. Even 2022 sets had already gained 46.5% within just 2-3 years of retirement. Compare that to a savings account earning 4-5% annually.

LEGO's Secret Weapon: Multi-Channel Value

Unlike stocks, LEGO sets can be sold across multiple platforms — and prices vary significantly. Here's how post-retirement prices compared across platforms for top-performing sets:

Prices reflect post-retirement market values as of early 2026.

Amazon and Walmart prices tend to run 20-60% higher than eBay sold prices for in-demand retired sets. Smart sellers diversify across platforms to maximize returns — something you simply can't do with a stock certificate.

The Risks: Why LEGO Isn't a Perfect Investment

Let's be fair — LEGO investing has real downsides compared to stocks and gold:

The Bottom Line

LEGO won't replace your 401(k), but as an alternative asset class, the numbers speak for themselves. An average 75% appreciation across 2,123 sets — with outliers exceeding 8,000% — makes LEGO one of the most compelling alternative investments available to everyday collectors.

The key is knowing which sets to buy and when. That's exactly what BrickBucks helps you do.
