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 Class | Avg. Annual Return | 10-Year Total Return | Best Single Asset Return |
|---|---|---|---|
| LEGO (Retired Sets) | ~11-12% | 75% avg. appreciation | 8,020% (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 Year | Sets Tracked | Avg. Appreciation | Avg. Profit Per Set |
|---|---|---|---|
| 2018 | 310 | 153.0% | $56.46 |
| 2019 | 303 | 99.3% | $38.81 |
| 2020 | 281 | 77.1% | $39.88 |
| 2021 | 299 | 51.3% | $25.73 |
| 2022 | 292 | 46.5% | $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.
| Set | Retail | eBay | Amazon | Walmart |
|---|---|---|---|---|
| 75274 TIE Fighter Pilot Helmet | $59.99 | $353 | $473 | $474 |
| 10251 Brick Bank | $169.99 | $699 | $845 | — |
| 75810 The Upside Down | $199.99 | $805 | — | $1,296 |
| 75281 Anakin's Jedi Interceptor | $29.99 | $144 | $180 | $180 |
| 21163 The Redstone Battle | $39.99 | $229 | $299 | $300 |
| 70670 Monastery of Spinjitzu | $79.99 | $335 | $310 | $280 |
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 Star Performers
Here are the LEGO sets that would have made any portfolio manager weep with envy:
Best Overall Returns
- 21038 Las Vegas (Architecture, 2018) — $39.99 retail, reached $3,247 after retirement. That's an 8,020% return. A $1,000 investment would have been worth $81,200.
- 42113 Bell-Boeing V-22 Osprey (Technic, 2020) — $149.99 retail, climbed to $1,368. 1,040% return within 5 years, driven by LEGO pulling the set due to controversy.
- 10251 Brick Bank (Creator Expert, 2016) — $169.99 retail, reached $845 on Amazon. 311% return from the iconic Modular Buildings line.
Best Dollar-Adjusted Returns
- 75226 Inferno Squad Battle Pack — $14.99 retail, reached $89 on Walmart. Small investment, big percentage gain.
- 76168 Captain America Mech Armor — $9.99 retail, reached $76 on Amazon. A $10 set that 7x'd.
- 21148 Minecraft Steve BigFig with Parrot — $14.99 retail, reached $100 on Amazon. Nearly 7x return.
The Risks: Why LEGO Isn't a Perfect Investment
Let's be fair — LEGO investing has real downsides compared to stocks and gold:
- Storage costs — You need space. A diversified LEGO portfolio can fill a room.
- Liquidity — Selling takes effort. You can't dump a LEGO set with a single click like a stock.
- Condition sensitivity — A dented box or broken seal can slash value by 30-50%.
- No dividends — LEGO doesn't pay quarterly dividends. All returns come from appreciation.
- Not all sets appreciate — While the average is 75%, some sets barely break even or lose value.
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.
