Supply Shocks And Premium Compression In Physical/Numismatic Metals
Sources: 1 • Confidence: Medium • Updated: 2026-03-27 10:10
Key takeaways
- A large new supply can raise prices for truly desired rare items (“supply creates demand”) while pushing down prices for already-common items by making them even more common.
- Modern U.S. coin grading commonly uses a 1–70 Sheldon-based scale, with Mint State grades from MS60 to MS70 for uncirculated coins.
- Over the last 10–15 years, the rare coin market has bifurcated: demand is strong for top-quality, truly rare “trophy” coins while demand for more common coins has largely disappeared.
- The internet reduced the need to attend coin shows to source inventory, leading Van Simmons to go far less frequently than before.
- A torn-in-half sports card was authenticated/graded as real and sold for about $1 million.

Supply Shocks And Premium Compression In Physical/Numismatic Metals
- A large new supply can raise prices for truly desired rare items (“supply creates demand”) while pushing down prices for already-common items by making them even more common.
- Premiums on lower-grade common-date U.S. gold coins have compressed as higher gold prices brought more supply to market, while truly high-grade examples have remained relatively strong.
- The hoard reportedly includes many U.S. $5, $10, and $20 gold coin issues from 1850 onward across mint marks, and was estimated at roughly $4–$5B in value.
- The hoard reportedly included about 80–90 examples of the scarce 1850 $20 gold piece.
- A multi-billion-dollar hoard of U.S. gold coins was discovered and introduced to the market in recent years, increasing supply for many dates.
- The gold market has shifted from mostly one-way buying interest to a more balanced two-way market with many more sellers at today’s higher prices.
Grading/Certification As Market Infrastructure And Incentive Design
- Modern U.S. coin grading commonly uses a 1–70 Sheldon-based scale, with Mint State grades from MS60 to MS70 for uncirculated coins.
- For older coins made with pre-modern minting methods, perfect MS70 grades are effectively nonexistent, while modern computer-controlled minting can produce near-perfect grades.
- PCGS launched in 1986, and within roughly 30–60 days the market broadly required PCGS-graded coins for easy sale because PCGS guaranteed grades and would buy back misgraded coins.
- Within the same numeric coin grade (e.g., MS65), there are meaningful quality tiers (A through D), and the market uses concepts like “plus” grades for higher-end examples.
- The extreme value of top 1952 Topps Mickey Mantle cards is claimed to be driven by grade scarcity, with a claim that PSA had graded only three copies as “10.”
- The coin industry resisted computerized grading because many collectors repeatedly resubmit coins hoping for an upgraded grade, and grading subjectivity benefits that behavior.
Collectibles Bifurcation: Trophy Liquidity Vs Mid/Low-End Illiquidity
- Over the last 10–15 years, the rare coin market has bifurcated: demand is strong for top-quality, truly rare “trophy” coins while demand for more common coins has largely disappeared.
- Premiums on lower-grade common-date U.S. gold coins have compressed as higher gold prices brought more supply to market, while truly high-grade examples have remained relatively strong.
- COVID-era production disruptions reportedly reduced Rolex output materially (cited as ~80% decline), driving sharp price increases in modern watches, while high-end vintage watches remain very liquid with rapid sales at six-figure-plus prices.
- In sports cards, items under roughly $100,000 are currently hard to sell while items above $100,000 are described as very liquid.
- Sports cards produced after about 1975 tend to be common and relatively illiquid compared with older issues.
- For certain trophy collectibles, Van Simmons argued there is effectively no price resistance because there is so much money seeking such items.
Market Microstructure Shifts: Online Sourcing, Dealer Networks, And Venue Fragmentation
- The internet reduced the need to attend coin shows to source inventory, leading Van Simmons to go far less frequently than before.
- Coin shows can concentrate billions of dollars of portable wealth under one roof, and attendees may carry anywhere from about $1,000 to $5 million in a small box.
- At a recent Long Beach coin show, Van Simmons says one dealer accounted for about 90% of his sales by purchasing boxes of high-quality coins for that dealer’s clients.
- There is no single coin show that serves as a definitive “Super Bowl of coins” because major events are regional and spread across the calendar.
- Meb Faber states that his rare-coin inventory typically rotates about every 11 days and items not sold within roughly 60–90 days are discounted and cleared.
- The January Florida United Numismatists “FUN Show” in Orlando is identified as one of the largest U.S. coin shows of the year.
Extreme-End Price Formation In Trophy Markets
- A torn-in-half sports card was authenticated/graded as real and sold for about $1 million.
- The extreme value of top 1952 Topps Mickey Mantle cards is claimed to be driven by grade scarcity, with a claim that PSA had graded only three copies as “10.”
- Van Simmons described a price progression for the 1952 Topps Mickey Mantle PSA 10 from about $50,000 in the early 2000s to about $5 million roughly 10 years ago and to an estimated $50–$60 million buyer range about a year ago, and also cited a $15 million sale for a PSA 9.
- For certain trophy collectibles, Van Simmons argued there is effectively no price resistance because there is so much money seeking such items.
- In 1983, Van Simmons instructed a partner to buy as many 1952 Topps Mickey Mantle cards as possible that could grade mint after prices fell from about $3,000 to about $1,000–$1,500.
- About seven to eight years after buying 1952 Topps Mickey Mantle cards for roughly $1,000–$1,500, comparable cards were trading around $7,000–$10,000.
Watchlist
- A recession or bear market could reduce discretionary purchases of high-end collectibles, especially those tied to wealth effects from stock market highs.
Unknowns
- What independently verifiable evidence exists for the claimed multi-billion-dollar U.S. gold coin hoard (size, composition, dates, dispersal schedule)?
- Do grading-service population reports and auction appearance frequencies show measurable step-changes consistent with the hoard narrative for affected series/dates?
- How stable is the stated sports-card liquidity threshold around $100,000 across venues and time, and what are clearance rates by price tier?
- What are the actual current bid/ask spreads and time-to-sale metrics for ‘trophy’ versus ‘common’ coins/cards/watches, and how do these change in drawdowns?
- Is ‘junk silver at discount to spot’ widespread, and what is the current smelter/refinery backlog as measured by quoted turnaround times and capacity utilization?
