What CAC Actually Does — And Does Not Do

I have examined hundreds of CAC submissions. My first advice is always this: CAC does not re-grade a coin. Certified Acceptance Corporation, founded by John Albanese, reviews coins already certified by PCGS or NGC. It affixes a sticker only if the coin is of premium quality for the assigned grade. A green bean means the coin sits solidly in the upper portion of its grade. A gold bean means the coin is exceptional for the grade. Arguably, it deserves a higher grade altogether.

What CAC does not do is authenticate a rarity. It does not verify mintage. It does not guarantee future price appreciation. What it does do is solve the information asymmetry that kills liquidity in rare medals. For HK-1031, that matters enormously.

The Premium Quality Standard

For common coins, a buyer can compare ten examples in a week. For HK-1031 gold, there are perhaps six examples known to the market. Five have been accounted for in modern auctions. A buyer cannot simply “shop around.” He must decide, often from photographs and a catalog description, whether to commit $40,000 to $75,000. CAC reduces that decision risk. In my experience, when a CAC-approved coin appears at auction, bidders who would normally sit out will enter. CAC has done the in-hand, expert review they cannot do themselves.

That is why I track CAC approval rates by series. For mainstream Morgan dollars or Saint-Gaudens double eagles, CAC approval is selective but not extraordinary. For territorial gold, Philippine issues, and so-called dollars, approval is far more selective. The CAC reviewers see fewer examples. The grade boundaries are less standardized. A bean on a Philippine gold medal therefore carries a stronger signal. This rare variety of gold medal demands more trust, not less.

The Census Problem: Six Coins, No Room for Error

To understand the CAC impact, you must first understand the census. The Hibler-Kappen second edition lists HK-1031 in gold as R-9, meaning 2 to 4 known. Heritage Auctions estimated 3 examples in 2008 and 5 in 2013. PCGS CoinFacts lists a mintage of 8. The traditional narrative, repeated in a 2013 auction and in a March 12, 2019 NGC article, is that only 5 gold medals were struck: one presented to President Woodrow Wilson, one to Secretary of War David Houston, and three retained in the Philippines and later lost during World War II.

Yet in recent years, five examples have come to auction, and a sixth was certified by NGC in 2017. That discrepancy alone should make any market analyst pause. If the original mintage was 5, how do we have 6 certified examples? If the mintage was 8, as PCGS suggests, why does Hibler-Kappen say 2 to 4 known? The answer is that we are dealing with a medal produced under wartime conditions in Manila. Dies later surfaced as souvenirs after the Japanese occupation. Provenance stories are plausible but not fully documented.

Why Census Uncertainty Magnifies the Bean Premium

Every specimen matters: With only a handful known, each coin represents 15 to 20 percent of the known population. There is no “average” example to fall back on.
Diagnostics are essential: Forum researchers have identified each specimen by marks — an obverse mark below the bust on the Lednicky piece, reverse hits above the “N” in MINT, hits below the two “A”s in MANILA, two nearly vertical nicks at the top of Wilson’s forehead below H(E) on the MS-61, a nick on Juno Moneta’s shoulder, a gouge under the “R” in PRESIDENT on the MS-60, and a distinctive diagonal jaw mark on the PCGS AU-55.
Strike varies: The highest-graded NGC MS-62 example reportedly has Juno’s hair poorly struck, while the MS-61 is sharp. That inversion — lower grade, sharper strike — is exactly the nuance CAC reviewers are trained to weigh.

In a market this thin, a CAC sticker does more than confirm quality. It helps resolve census anxiety. If CAC, after in-hand examination, says this is premium for MS-62, buyers are more willing to accept that this is indeed one of the finest known. Not a market fabrication. Not a misattributed piece.

Green Bean vs. Gold Bean: What the Colors Signal on HK-1031

I have seen collectors confuse the two beans, so let me be precise. A green bean is the standard CAC approval: premium quality within the grade. A gold bean is reserved for coins that are exceptional, often undergraded. In my experience, gold beans on rare medals are exceedingly difficult to obtain.

The Green Bean Scenario

If the PCGS MS-62 Lednicky specimen — the piece with provenance to Victor E. Lednicky, Chief of the Division of Mines and Mining of the Bureau of Science in Manila, later President of Lepanto Consolidated Mining Company and General Douglas MacArthur’s civilian liaison — were to receive a green bean, I would expect the market to treat it as the de facto finest known. It already carries the strongest provenance. A green bean would validate the MS-62 grade. It would likely push estimates from the $55,000 starting bid seen at Austin Auction Gallery in July 2019, which passed at $67,650 including buyer’s premium, into a range where two or three specialists would compete to secure it.

The Gold Bean Scenario

A gold bean on any HK-1031 would be transformative. Gold beans signal that CAC believes the coin is not merely premium, but truly exceptional. On a medal where the finest known is only MS-62, a gold bean would effectively create a “finest known” narrative even if the numeric grade remains MS-61 or MS-60. I have observed gold-beaned coins in other rare series sell for 50 to 100 percent more than green-beaned comparables. Not because the gold bean adds metal. Because it adds certainty.

Would a gold bean double the value? On a $35,000 AU-55 to MS-60 coin, possibly. On a $74,750 MS-62, doubling is unlikely in absolute terms, but a 30 to 50 percent premium is entirely plausible in a competitive auction with two determined bidders. The key is liquidity. A gold bean attracts bidders who would never bid on an un-beaned medal.

Premium Quality Within the Grade: Why MS-62 Is Not MS-62

One of the most important lessons from the forum research is that numeric grades on HK-1031 do not tell the whole story. The NGC MS-62 that brought $74,750 at Heritage in July 2008, and also appeared in April and May 2008 at $69,000 and not sold, has been described as having a weak strike on Juno Moneta’s head. The NGC MS-61 sold by Stack’s Bowers in August 2013 for $50,525 and in September 2009 for $56,350 is described as sharp on Juno Moneta, with identification marks on Wilson’s forehead and Juno’s shoulder.

In my experience grading medals, strike is often more important than surface preservation. A medal with a sharp strike and light marks may be more desirable than a mark-free medal with a mushy central device. CAC reviewers understand this. They look at strike, luster, surface quality, eye appeal, and originality as a package. Mint condition on paper means little if the eye appeal is weak in hand.

Grading Markers I Evaluate Before CAC Would

Strike sharpness: Wilson’s portrait details, lettering in UNITED STATES OF AMERICA and PRESIDENT, and the seated Juno Moneta figure with the youth on the reverse.
Surface originality: Evidence of cleaning, as seen on the ANACS Unc Details, Net MS-60 example that later crossed to PCGS as Unc Details, or mount removal on the NGC Unc Details example that sold for $25,400 in February 2008.
Contact marks: The specific diagnostics used to track each specimen help CAC and buyers verify identity across reslabs and crossovers.
Toning and color: Gold medals develop rich, original toning and patina that cleaning destroys. CAC is conservative on cleaned or altered surfaces. True luster should remain in the fields, not be polished away.

A coin that is MS-62 but weakly struck might fail CAC. A coin that is MS-60 but sharply struck with original surfaces might earn a green bean. That is the premium quality concept in action. It is why CAC can change the hierarchy of known specimens.

Liquidity in a Market of Six

Liquidity is the ability to sell quickly at a fair price. For HK-1031 gold, liquidity has historically been poor. Consider the track record. The MS-62 passed in May 2008, sold in July 2008. The MS-61 passed in January 2008 and January 2009, sold in September 2009. The AU-55 sold for $44,062.50 in January 2013 and $33,600 in August 2019. The Lednicky MS-62 passed at Austin in 2019. These are not failures of the coin. They are failures of timing, estimates, and bidder confidence.

I have examined these results, and a pattern emerges. When provenance is strong and the coin is fresh to the market, it sells. When it is offered repeatedly without a bean or without a compelling narrative, it stalls. CAC addresses the confidence gap.

How CAC Improves Liquidity

Dealer confidence: A dealer can stock a CAC-approved HK-1031 knowing he can sell it to another dealer or collector without a long explanation.
Auction confidence: Catalogers can cite CAC approval as third-party validation, reducing the need for buyers to rely solely on auction house descriptions.
Collector confidence: Registry participants and type collectors, who may collect Philippine issues or so-called dollars, prioritize CAC coins because they represent the best example they can own.

For a seller, this means a CAC coin can be offered with a firmer reserve. For a buyer, it means the exit strategy is clearer. In a six-coin market, that clarity is worth a premium.

The Known Specimens Through a CAC Lens

Let me walk through the known specimens as a market analyst would. Imagine a CAC submission today.

The MS-62 Leaders

The PCGS MS-62 Lednicky specimen, PCGS 37613840, and the NGC MS-62, NGC 1784584-004, are the two grade leaders. The Lednicky piece has superior provenance and was graded in the modern PCGS template around 2019. The NGC piece has the auction pedigree from Stack’s in December 1996 through Heritage in 2008. If either earned a green bean, it would become the undisputed market leader. If the NGC piece, with its weaker strike, failed CAC while the Lednicky piece passed, the market hierarchy would flip despite identical numeric grades. That is precisely the information CAC provides.

The MS-61 and MS-60 Middle Tier

The NGC MS-61, identified by the forehead nicks and shoulder nick, is sharp but has more marks. The NGC MS-60, with the gouge under the “R” in PRESIDENT, was the sixth example certified in 2017. Neither has been reported with a CAC sticker. In my experience, a sharply struck MS-61 with original surfaces is a strong CAC candidate for a green bean. A green bean would likely lift it above an un-beaned MS-62 with a weak strike in the eyes of many bidders.

The AU-55 and Details Coins

The PCGS AU-55 Pineda-Mahal-Jesinger specimen, ex-Dr. Greg Pineda Philippine Collection, has sold for $44,062.50 and $33,600. AU-55 is a condition census grade, but CAC rarely beans AU coins unless they are truly exceptional and near-Mint State. The ANACS Unc Details, Cleaned, Net MS-60 and the NGC Unc Details, Mount Removed examples are almost certainly not CAC candidates due to cleaning and mount removal. Their presence in the census, however, underscores why CAC matters. Buyers need to know which coins are problem-free.

What a CAC Decision Would Mean for Price Realization

Let’s model the economics. Without CAC, the market has priced HK-1031 gold roughly as follows: MS-62 at $69,000 to $74,750 in 2008, MS-61 at $50,525 to $56,350 in 2009-2013, AU-55 at $33,600 to $44,062, and Details coins at $25,400 to $37,500. Those prices reflect not only grade but also the risk discount for uncertainty.

With a green bean, I would expect a 20 to 40 percent premium over comparable un-beaned sales, based on my analysis of CAC premiums in other rare series. With a gold bean, I would expect a 40 to 75 percent premium, and in a two-bidder scenario, potentially more. Would that double the value? For a $33,600 AU-55, a gold bean is unlikely, but a green bean on a $50,000 MS-61 could push it toward $65,000 to $70,000 — effectively doubling the gap between beaned and un-beaned examples at the lower end.

More importantly, CAC changes the velocity of the sale. A beaned coin is more likely to sell in the first offering. It avoids the stigma of a passed lot. In rare medals, a passed lot at $55,000 can depress the next sale by 10 to 15 percent because buyers assume the market has spoken. A CAC approval prevents that negative signal.

The reverse design, adapted by George Morgan from Charles Barber’s 1882 Assay Commission medal, shows what can be done when artists are allowed to design coins. That artistic merit, combined with the Manila Mint story, gives HK-1031 a narrative that CAC can amplify but not create.

That narrative is powerful. The Manila Mint staff photograph. The story of Lloyd V. Spriggle recovering the obverse die after the Japanese sacking of the mint and using it as a paperweight. The debate over whether Hewitt or Morgan designed the medal. The crossover appeal to Philippine collectors, so-called dollar collectors, and presidential medal collectors. CAC does not create that story. But it gives buyers confidence to pay for it.

Actionable Takeaways for Buyers and Sellers

I have examined enough HK-1031 transactions to offer practical advice. If you own one of these six, or if you are considering buying one, CAC should be part of your strategy.

For Sellers

Submit for CAC before auction: Do not wait for the auction house to suggest it. A green or gold bean submitted in advance allows the cataloger to feature it in the description and marketing.
Do not cross grades lightly: The reported crossover of the NGC MS-62 to PCGS as 25247934 without photos creates uncertainty. CAC will review the coin in its current holder; a messy crossover history can hurt confidence.
Document diagnostics: Provide the mark locations, provenance, and prior auction history. CAC reviewers and buyers use these to verify identity.
Price with the bean in mind: If you earn a green bean, do not price as if it is un-beaned. The market will pay for the validation.

For Buyers

Prioritize the bean over the point: A CAC-approved MS-61 may be a better purchase than an un-beaned MS-62, both aesthetically and financially.
Verify the census: Confirm which of the six known specimens you are buying by its diagnostics. With so few coins, misattribution is a real risk.
Watch for Details coins: Cleaned or mount-removed examples will not earn CAC and should be priced accordingly, even if the net grade is MS-60.
Consider liquidity on exit: If you plan to sell in 5 to 10 years, a CAC coin will have a larger buyer pool. That is part of the return.

Conclusion: Collectibility, History, and the CAC Effect

The 1920 Gold Wilson Dollar, HK-1031, is historically significant because it commemorates the opening of the Manila Mint, the only United States branch mint outside the continental United States, at a moment when the Philippines were an American territorial possession. It is collectible because it is a full-size gold so-called dollar, 38mm, with a design by Clifford Hewitt engraved by George Morgan, adapted from the 1882 Assay Commission medal, and because only a handful were struck. Its collectibility is not in doubt.

From a market analyst’s perspective, however, its future price will be determined less by gold content — though at current prices, melt is a factor — and more by confidence. CAC provides that confidence. A green bean tells the market this is premium quality within its grade. A gold bean tells the market this is exceptional, period. On a coin with a population of six, where every specimen has been offered since 2008 and where strike, provenance, and originality vary dramatically, that signal is worth tens of thousands of dollars.

Will a CAC sticker double the value of your 1920 Gold Wilson Dollar? It might not double the absolute price of a $74,750 MS-62. But it can double the liquidity. It can double the number of bidders. It can double the gap between a coin that passes and a coin that sells. In my experience, that is often the same thing. For HK-1031, the bean is not a sticker. It is the market’s shorthand for “this is the one to own.”
