Collectibles are gaining attention as alternative investments that may offer substantial growth and low correlation with traditional assets. From rare coins and classic cars to fine art and pop culture memorabilia, collectors worldwide are discovering that tangible assets can deliver both financial and aesthetic rewards. This extensive post discusses which collectibles have performed strongly, the risks tied to them, and how they might fit into a balanced portfolio.
Collectibles have entered the mainstream of portfolio management. These real-world assets, once limited to niche enthusiasts, now attract global investors looking for growth and a hedge against the volatility of stocks and bonds. Classic cars, fine art, sports memorabilia, luxury watches, wine, NFTs, and rare coins have all shown the potential for healthy returns over various timeframes. In many cases, their performance is not closely linked to the fortunes of the equity or bond markets, which adds to their appeal. This piece aims to guide readers through the key points to consider before adding collectibles to an investment mix, while also highlighting record-breaking sales that reinforce how valuable certain objects can become.
Fine art and antique coins have always attracted interest, but the variety of collectible categories has expanded immensely. Now, everything from vintage comic books to first-edition sneakers can achieve eye-popping price tags. Part of the shift is driven by global wealth growth: more high-net-worth individuals are willing to place money into tangible assets, and emerging markets in Asia, the Middle East, and elsewhere have become significant players in auctions worldwide.
High-profile headlines reflect this enthusiasm. A single baseball card featuring Mickey Mantle sold for $12.6 million. A 1955 Mercedes-Benz 300 SLR reached $142 million in 2022, setting the all-time auction record for a car. Iconic paintings by da Vinci and Picasso have commanded hundreds of millions. In collectible wine, certain Bordeaux and Burgundy vintages have multiplied in value. NFTs have sparked debates over the definition of ownership, yet some early buyers realized triple- or quadruple-digit returns before the market cooled.
While spectacular examples exist, it’s important to examine broader data on returns, volatility, and market correlations. This article distills that information to help readers decide how collectibles might benefit a portfolio.
What is this post about
This post compiles data from auction houses, global indices that track collectible categories, and historical trends observed in government statistics. We look at approximate annual returns for multiple classes, focusing on timescales ranging from the past 10 years to broader 20- or 50-year windows where such data is available. We also incorporate anecdotal evidence of record-breaking sales, which highlight the remarkable gains possible in these markets.
Although each collectible niche has its own dynamics, from supply and demand to cultural significance, this overview provides a comprehensive picture of how these assets perform and why they appeal to those seeking alternative investments.
1. Historical Performance of Collectibles vs. Traditional Assets
Many collectibles have produced annual returns that are competitive with, and sometimes exceed, the gains seen in traditional markets. Historical analyses suggest fine art often grows at around 7% annually over the long term. Classic cars, tracked by multiple car-focused indices, appear capable of delivering annual returns near 10–11%. Vintage Ferraris and Mercedes have led the charge in recent years with some spectacular multi-million-dollar sales.
Luxury watches—think Patek Philippe, Rolex, and Audemars Piguet—generally return around 9% per year, supported by a steadily growing secondary market. Fine wine shows similar gains, hovering near 9%, and certain highly rated vintages can outperform the average. Rare coins, particularly historically significant pieces or those with extremely low mint numbers, often match or exceed 10% annually. Trading cards, driven in part by nostalgia and pop culture, have reached double-digit returns at times. NFTs have less of a track record, though some soared to 5% or more monthly returns early on, only to swing wildly as sentiment changed.
For reference, major equities in the U.S. have returned close to 9.7% annually over many decades, bonds around 5%, gold around 7.5%, and real estate near 8%. The bar chart below (Graph 1) compares average annual returns for multiple collectible categories and key traditional assets.

2. Investment Metrics: Returns, Volatility, and Liquidity
Returns alone do not paint the full picture. Each collectible niche has its own pattern of volatility. Fine art typically experiences price swings in the 15% range. Classic cars can spike or tumble more sharply, around 20%. Trading cards, especially popular ones such as vintage baseball or Pokémon cards, have realized around 25% volatility due to sudden shifts in collector enthusiasm. NFTs can reach a striking 80% volatility, reflecting wide speculative jumps.
By contrast, stocks have a volatility near 17%, bonds around 6%, and real estate about 10%. Fine wine, with volatility around 5%, stands out as one of the steadier collectible categories. Some experts attribute that to consistent demand among wealthy buyers and limited annual supply, notably for highly rated Bordeaux or Burgundy.
Liquidity also varies. Selling a rare piece of art might involve waiting for a suitable auction event. Vintage cars, though in demand, are not easily sold overnight. In contrast, certain coins, watches, and trading cards can change hands more quickly, aided by established grading systems and recognized pricing guides. Still, none of these categories achieve the near-instant liquidity of stocks or gold. Two charts (Graphs 2 and 3) provide visual overviews of the volatility and liquidity differences among collectibles and traditional investments.
3. Correlation of Collectibles with Traditional Assets
One of the strongest arguments for adding collectibles to a portfolio is their generally low correlation with stocks and bonds. Fine art often exhibits a correlation near 0.12 versus major equity benchmarks, while classic cars, rare coins, and other categories also hover around near-zero or modestly positive correlations. In theory, this means that a downturn in the S&P 500 does not necessarily translate to falling values for high-end paintings or collectible coins.
During periods of economic stress, liquidity may dry up for certain high-value items, but historical data points to the resilience of collectibles in many past recessions. Graph 3 below shows correlation coefficients between collectibles and the S&P 500. Even NFTs, which are very new, do not seem to track stocks in a consistent pattern.
4. Portfolio Allocation Strategies: Where Do Collectibles Fit?
Modern Portfolio Theory suggests that including a small proportion of low-correlation assets can improve an investor’s risk-return profile. A typical guideline is to commit around 5–10% of one’s portfolio to collectibles, though this can vary by risk tolerance. Going above that level can increase the challenge of liquidity and price uncertainties, unless one has very specialized knowledge.
Diversifying within collectibles is also advised. If a person wants to allocate 10% of their portfolio to this space, they might allocate 30% of that portion to fine art, 20% to classic cars, 15% to watches, 15% to fine wine, 10% to rare coins, 5% to trading cards, and 5% to more speculative segments like NFTs or precious minerals. This spread can soften category-specific downturns. Graph 4 illustrates a recommended breakdown that balances potential returns with relative risk.
5. Historical Performance Trends: A Time Series Comparison
The following line chart (Graph 6) tracks performance from 2013 to 2023 for a Fine Art Index, the S&P 500, and a Gold Index. In many stretches, fine art has kept pace with or even outperformed equities, providing an alternative growth path for investors. Precious metals like gold also play a safe-haven role, but art’s scarcity can at times generate higher demand from affluent collectors even when markets stumble.
Classic cars have staged dramatic climbs in certain eras, particularly between 2010 and 2016, where some iconic models more than quadrupled in value. While this excitement cooled somewhat in subsequent years, key auctions for rare vehicles still reach staggering figures. Fine wine has also performed steadily, occasionally outpacing mainstream markets during turbulent periods.
Does investing in collectibles fit you?
The wide array of collectibles—from ancient coins to contemporary NFT artworks—means that there is no one-size-fits-all approach. Yet the data repeatedly shows these assets can generate healthy returns that sometimes surpass stocks, bonds, or real estate. Many seasoned collectors stress the importance of buying quality. A top-tier example of a vintage watch, an authentic painting by a recognized artist, or a historically significant sports card tends to hold value better than run-of-the-mill items. Rarity and condition are major drivers of price.
Historic sales remind us of the market’s potential:
- Leonardo da Vinci’s Salvator Mundi selling for $450.3 million after being bought for under $10,000 decades prior (pre-authentication).
- A 1952 Topps Mickey Mantle card purchased for a modest sum that later fetched over $12 million.
- A Mercedes-Benz 300 SLR “Uhlenhaut” Coupé commanding $142 million at an auction.
- Fine wine from top Châteaux delivering multi-fold returns for patient collectors over a decade or more.
These numbers draw attention, yet everyday transactions also shape the market. Owners of vintage coins or well-regarded mid-tier art pieces have often seen consistent appreciation, though not at the explosive rates headline sales might suggest. The intangible benefit of collecting what one appreciates—be it watches or rare stamps—adds another dimension to the investment.
Risks do exist. Authentication is crucial. Forgeries and misrepresented items plague various segments, from fraudulent signatures on sports memorabilia to questionable painting attributions. Many items also require proper storage and insurance (particularly art, wine, and classic cars). Selling can involve lengthy wait times and steep auction fees. These factors highlight the need for realistic expectations and a focus on due diligence.
Collectibles have proven their place as an alternative investment, offering both tangible pleasure and portfolio benefits. Data indicates that many categories can match or outpace equities over the long run. Crucially, the low correlation with traditional assets helps enhance diversification. When stocks or bonds face challenges, collectibles might hold their ground or even climb, as high-net-worth buyers continue to seek unique items.
It is advisable to keep allocations moderate and to select items based on careful research into authenticity, provenance, and market trends. In many instances, these assets require patience and a multi-year holding horizon. The best outcomes often arise when a collector genuinely appreciates the object and understands its nuances, from the way a classic car’s historical significance affects pricing to how a particular artist’s reputation impacts a painting’s value.
For investors who accept the challenges and remain methodical in their approach, collectibles can serve as a fascinating, and potentially lucrative, addition to a broader portfolio. The longevity and cultural weight of these assets set them apart from more conventional holdings, and the stories behind each rare acquisition can be as meaningful as the returns themselves.
