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?

Investor overlay

Read-throughs

  • If new supply enters numismatic markets, premiums on common date and lower grade coins may compress versus spot, shifting trading activity and price discovery toward truly rare trophy items and away from mid tier inventory.
  • Collectibles markets may behave as separate liquidity pools. Trophy assets could retain liquidity while common material becomes harder to exit, increasing dispersion in realized prices, spreads, and time to sale across tiers.
  • If AI based grading gains trust, subjective resubmission economics may change, potentially reducing repeated submissions and altering value differences within the same grade label, affecting market liquidity and pricing granularity.

What would confirm

  • Grading service population reports and auction appearance frequencies show step changes for specific series and dates consistent with a large hoard driven supply increase.
  • Observed bid ask spreads and time to sale widen for common coins and mid tier collectibles while remaining relatively tight for trophy quality items, especially during market drawdowns.
  • Evidence of premium compression appears in dealer quotes, auction results, or reported discounts to spot for common silver and gold items, alongside measurable changes in refinery turnaround times.

What would kill

  • No independently verifiable evidence emerges for the hoard size, composition, and dispersal schedule, and population reports and auction frequencies show no meaningful shift versus historical baselines.
  • Liquidity does not bifurcate in practice, with similar clearance rates, spreads, and time to sale across trophy and common tiers, including during periods of weaker risk appetite.
  • AI grading adoption remains limited or not trusted, and resubmission behavior and within grade price dispersion do not change materially versus prior patterns.
