By Mike Byers for Mint Error News ……
The PCGS Price Guide valued this unique Eisenhower Dollar long ago at $850,000 USD. Today, Mike Byers estimates the value well into seven figures.

The 1976 Type 2 “No S” Silver Proof Eisenhower Dollar is one of America’s great mystery coins! It is a 1976 Proof Bicentennial dollar lacking the “S” mintmark for San Francisco, and was discovered at a Woodward & Lathrup department store in the Washington, D.C. area in 1977.

It is possible that this coin was struck as a presentation piece for a government or White House official in Washington and then entered circulation when it was accidentally spent.

Mitchell Spivack of Wondercoins is the owner of this unique Eisenhower Dollar and he exclusively commented on this coin for the readers of Mint Error News:

For the better part of around 10 years, PCGS has valued the Unique 1976 Type 2 “No S” Silver Proof Eisenhower Dollar at $850,000 in its Price Guide. This value was established well before I bought and then immediately resold one of the two known 1975 “No S” Dimes at public auction back in September 2019 for $516,000 (it had previously sold for around $350,000). Additionally, several other Eisenhower dollars have recently traded well into six figures at public auction. The Ike dollar series has really “taken off” and has come into its own!

Based upon the recent upward trajectory of the (current) mintage two 1975 “No S” Dimes, as well as many Eisenhower Dollars now being worth in excess of six figures, I currently believe that the 1976 Type 2 “No S” Silver Proof Eisenhower Dollar is a “strong seven figure” coin. I receive, on average, at least one random, unsolicited, communication a day from across the globe from non coin collectors who believe they have found another “holy grail” 1976 Type 2 “No S” Silver Proof Eisenhower Dollar. Of course, they have all found, to date, simply one of the millions and millions of business strike Type 2 Eisenhower Dollars produced in Philadelphia in 1976. But the word is spreading fast, especially via social media platforms such as YouTube, about the “holy grail” of Eisenhower Dollars – the Unique 1976 Type 2 “No S” Silver Proof Eisenhower Dollar! The 250th Anniversary of this great country is now less than three years away when this special coin will turn 50 years old!

1976 “No S” Bicentennial Proof Eisenhower Dollar – Provenance and Price History

The first sale was by Devonshire, raw, in 1982. It sold for $5,000. Martin Paul and Andy Lustig joint ventured it. It was subsequently sold to Alan Hager. Then it was certified PF65 by NGC. Martin Paul re-acquired it. It was in a Superior Auction, lot #1794, NGC PF65 in 1997.

At some point it upgraded to PCGS PR66. Then it was in a Bowers and Merena auction, lot #647, realizing $41,400 in 2002. Acquired by Mitchell Spivack. Re-designated CAMEO by PCGS.

Mint Error Coins News Magazine #68 Features Unique U.S. Errors

Mint Error News Magazine Issue 68: Unique U.S. Proof, Specimen, Pattern & Error Coins

 

Many numismatists, dealers, and collectors consider unique coins to be the most coveted, prized, and valuable. Many of these unique coins were documented by the United States Mint or one of the Mint branches, while others have no documentation at all but there are logical assumptions as to how and why they were struck.

Some of the most famous American coins were struck under mysterious circumstances, and the story behind each coin’s production adds to their rarity, prestige, and value. Examples of these “mysterious” coins include pieces struck in Proof where only one example is known or a special specimen striking produced using polished dies. Many other unique and unusual coins are patterns, trial strikes, or mint errors.

Featured errors from Mint Error News Magazine issue #68.

This issue of Mint Error News showcases some of the unique U.S. coins struck as a Proof, as a specimen strike, as a piece de caprice, or as a deliberately produced mint error rarity.

Only Known Proof Bicentennial Eisenhower Dollar Major Mint Error

By Mike Byers for Mint Error News ……
This Proof Bicentennial Eisenhower dollar major Mint error is unique in many ways and has no equals. It is the only known Proof Bicentennial Ike Dollar major Mint error of any kind. It is the only known example to be double struck. There are no off-centers known, no off-metals known, no mated pairs known, and no double denominations known.

Even though non-Bicentennial Proof Ike Dollar major Mint errors are rare, there are examples known with several types of major striking errors.

A “Clover Leaf” set of Ike dollars struck on dimes sold in a Heritage auction for $105,000 USD; two mated pairs have sold for $40K and $75K; off-metals have sold for as high as $25K each; off-centers and double strikes at $25K as well; a unique Bronze Ike Dollar sold for $75K; and a unique Ike Dollar on a struck Bronze Medal sold for $40K in another Heritage auction.

This double struck Proof Bicentennial Ike Dollar is pedigreed to John Devine (“Lonesome John”), a famous pioneer in the field of Mint errors and was just certified by Numismatic Guaranty Company (NGC). It was previously unknown to the numismatic community and is just now being offered for sale.

It is in very choice Proof condition and has deep mirrored fields with a Cameo portrait and Liberty Bell. It has high eye appeal since the major devices on the second strike are fully struck. The Ike portrait, Liberty Bell, and moon are fully present – as well as the complete mottoes IN GOD WE TRUST and E PLURIBUS UNUM.

Being the only known Proof Bicentennial Eisenhower Dollar major Mint error of any kind propels it into the rank of unique, amazing, and spectacular numismatic rarities.

It was featured on the cover of Mint Error News Magazine issue 67.

77% Cu, 20% Ni, 3% Mg – NGC (Mint State)

60.5% Ni, 32.5% Cu, 6.8% Fe – NGC (Proof)

* * *

The U.S. Patterns section on Mint Cancelled (waffled) Martha Washington trial pieces includes a total of six known with the new design. Two are the five-cent test pieces featured in this listing, one of which is the only one known in Proof. Two are five-cent test pieces that were struck in copper, one was featured in a 2018 Coin World article. And finally, two 25¢ test pieces, which includes my original discovery.

Newly redesigned Martha Washington dies were used to strike test pieces at the Philadelphia Mint in 2011 and 2013. These pattern coins were struck to test new metal compositions for the five-cent coin, in the event that Congress authorized a composition change. The rising cost of producing the nickel caused the Treasury some concern, but Congress acts very conservatively when it comes to change to the nation’s coinage.

These two five-cent test pieces with the Martha Washington “nonsense” designs were produced and have been assigned Judd #2210 and are listed on the U.S. Patterns website (uspatterns.com). Editor’s Note: The set is currently listed for sale for $25,000 on Byers’ website.
