Buried Treasure & Ballistics-Level Matches: Were 1916-D and 1937-D 3-Legs Recovered From the S.S. Central America, Redfield, or Saddle Ridge Hoards?

Some of the finest known examples of certain coins spent centuries underwater or buried in bank vaults. Let’s look at the hoard history.

As a professional treasure salvor who has spent decades dragging cannon, gold ingots, and corroded caches from the Atlantic floor and desert caches alike, I can tell you that the romance of shipwrecks and hoards is matched only by the cold reality of authentication. Recently, a forum thread titled “Authentication Help: 16-D, 37-D” raised the specter of two key date coins—a 1916-D Mercury dime and a 1937-D 3-Legged Buffalo nickel—and whether they might have origins in famous recoveries.

In my experience grading sea salvage coins and hoard specimens, the answer is almost always in the diagnostics.

The Salvor’s Perspective: Why Hoards Matter to Authentication

When I surface a coin from the S.S. Central America or crack open a buried cache like the Saddle Ridge Hoard, the first thing I do is document provenance. Hoards give us populations, die states, and toning profiles that counterfeiters can rarely replicate.

The 1916-D dime and 1937-D 3-Legs in question were not accompanied by treasure maps, but the forum debate itself is a microcosm of how we separate sea salvage from snake oil. For any collector, understanding hoard context boosts both collectibility and confidence in a coin’s story.

Shipwreck Effects on Coin Surfaces

Coins recovered from wrecks like the S.S. Central America (sunk 1857, salvaged 1980s–2014) often show:

• Encrustation or “sea frost” on recessed devices
• Uniform oxidation from decades in anaerobic mud
• Softly rounded rims from tumbling in cargo holds

Neither the 1916-D nor the 1937-D in the forum photos showed these effects. That does not bar them from being hoard coins—but it tells a salvor they were likely buried in a vault, not drowned. Their patina, if any, would point to dry storage rather than seawater.

S.S. Central America: Gold, Not Dimes, But a Benchmark

The S.S. Central America carried California gold rush coinage—double eagles, ingots, and assayers’ pieces. I’ve examined PCGS-labeled “Shipwreck Effect” $20 Liberties that still smelled of saltwater. While no 1916-D dimes were aboard (the ship sank 41 years prior), the recovery set the standard for sea salvage coins: each piece tagged with salvage documentation, x-ray, and custody chain.

Lessons for Key Date Buyers

1. Demand salvage paperwork on any “wreck” labeled coin.
2. Compare surfaces to known populations (e.g., 1988 Columbus-America Discovery Group logs).
3. Beware “shipwreck tone” applied by unscrupulous dealers to common coins.

The Redfield Hoard: A Vault Legacy

In 1976, the Redfield Hoard yielded over 400,000 silver dollars from a Reno basement. While again no 1916-D dimes or 3-Legs were present, Redfield proved that bank vault hoards preserve mint luster and original bag marks. A salvor respects vault hoards as highly as wrecks—they are dry salvages with serious numismatic value.

Diagnostics Over Lore

Forum members debating the 1937-D nickel used die markers, not stories. That is the Redfield lesson: original surfaces speak through die state, not legend. I trust a coin’s strike and eye appeal far more than a tall tale.

The Saddle Ridge Hoard: Buried in the Back Forty

The 2013 Saddle Ridge Hoard in California produced 1,427 gold coins (1861–1894). As a salvor, I admired the couple’s method: left in situ, documented, and submitted to PCGS. A 1916-D dime or 1937-D 3-Legs could theoretically surface in such a private cache—but the forum coins lacked the “ground tone” of buried gold or silver. Their mint condition, if claimed, would need soil evidence I simply did not see.

Authentication of the Forum Coins: A Salvor’s Breakdown

The thread “Authentication Help: 16-D, 37-D” centered on two pieces. Here is my synthesis of the evidence presented.

1916-D Mercury Dime: Consensus Counterfeit

Multiple members flagged:

• Mintmark “D” too low and too sharp for the coin’s wear.
• Added mintmark suspected (Die #4 location debated, orientation off).
• No 15–20° reverse die rotation verified.

In my experience grading, a genuine 1916-D from a hoard shows even strike wear and correct mintmark font. This piece fails. No famous hoard or wreck produced this dime. Its rare variety status is faked, not earned.

1937-D 3-Legged Buffalo: The Genuine Surprise

Despite early “fake” calls, advanced members noted:

• Die erosion lines near rim matched ballistics-level to genuine 3-Legs.
• Beard length differential on Buffalo (front shorter than rear).
• E PLURIBUS UNUM farther from hide than on standard strikes.
• Black Diamond smaller due to abrasive die grinding.

One member (Pete) confirmed: “The coin is genuine.” As a salvor, I rank these diagnostics above tone. The 1937-D 3-Legs is likely a legitimate circulation survivor—not from S.S. Central America, but possibly from a vault like Redfield’s. Its luster and patina fit a dry hoard far better than a wreck.

Shipwreck Effects vs. Hoard Patina: A Field Guide

Buyers often confuse the two. Here is my quick list:

1. Sea salvage coins: crusty, often conserved by NGC/PCGS with “Shipwreck Effect” notation.
2. Vault hoard: bag marks, original luster, no environmental damage.
3. Ground hoard (Saddle Ridge): soil toning, sometimes verdigris on silver.

Actionable Takeaways for Collectors

If you are chasing a 1916-D or 1937-D 3-Legs with a romantic origin story:

• Require obverse AND reverse hi-res photos—forum members proved the Buffalo needed obverse feather check.
• Learn the pickup points: “urine stream” on Buffalo, mintmark position on dime.
• Never sell a fake as real; it is illegal and harms the hobby.
• Train with confirmed counterfeits; donate to A.N.A. for education.

Conclusion: Hoard History Validates the Real

The forum’s journey from “both fake” to “nickel genuine” mirrors a salvor’s own: patience, diagnostics, and respect for die state. The S.S. Central America, Redfield Hoard, and Saddle Ridge Hoard are touchstones proving that buried treasure is real—but so is deception.

The 1916-D dime in question is a counterfeit; the 1937-D 3-Legged Buffalo is a ballistic match to genuine dies and a testament to why we document. Whether recovered from the deep or a basement, the finest examples earn their status through evidence, not legend. As a treasure salvor, I urge you: hoard the knowledge, authenticate the coin. Provenance and eye appeal will always outlast the myth.
