How to Find an 1866-S No Motto Seated Liberty Half Dollar

The 1866-S No Motto Seated Liberty half dollar is a short-lived transitional issue, struck at the San Francisco Mint in the narrow window before new dies bearing “IN GOD WE TRUST” arrived on the West Coast. PCGS reports roughly 30 examples known across all grades, with only a handful surviving in Mint State.

What makes the 1866-S No Motto half dollar important to collectors?

The Coinage Act of March 3, 1865, ordered the motto “IN GOD WE TRUST” added to gold and silver coins large enough to accommodate the inscription. Philadelphia and other facilities adopted the new dies relatively quickly, but new “With Motto” reverse dies weren’t sent to San Francisco until March 1866. In the meantime, the San Francisco Mint kept striking half dollars using its old No Motto reverse dies still on hand from the previous year.

That gap in shipping produced a small, unplanned issue: San Francisco struck about 60,000 No Motto half dollars in early 1866 before switching over to the new With Motto dies and striking roughly 994,000 pieces the rest of the year, mintage figures reported by PCGS CoinFacts. The No Motto coins that resulted are a genuine transitional rarity—hard to find in any condition and especially difficult in Mint State. PCGS reports about 30 known across all grades, with only about four reaching MS-60 or better and the finest known around MS-65; NGC’s population data likewise show only a couple of coins grading MS-60 or better. A notable example graded NGC MS67, from the Eric P. Newman collection, came to market when Heritage Auctions dispersed that collection in 2013–2014.

The coin is a die variety, not a mint error—it results from an entirely separate reverse die (lacking the motto) that was legitimately in service at the San Francisco Mint during the changeover, not from any striking mistake. That distinction, and the population data above, are the kind of variety attribution PCGS and NGC document in their online references for the Seated Liberty half dollar series.

How to identify an 1866-S No Motto half dollar

Confirm the “S” mint mark

A small “S” appears on the reverse, below the eagle.

Confirm the reverse lacks the motto

The key diagnostic is the absence of “IN GOD WE TRUST” on a ribbon above the eagle—present on the With Motto version struck later that same year, absent here. Compare the reverse carefully against reference images of both types, since the two 1866-S half dollars (No Motto and With Motto) are otherwise struck from similar Seated Liberty designs.

Examine overall wear and surface quality

Given how few examples survive in higher grades, small differences in preservation have an outsized effect on value. Look closely at Liberty’s figure, the shield, and the eagle for wear, and check for cleaning or other surface problems that would be less consequential on a more common date.

Know the physical specifications

Per U.S. Mint records and PCGS CoinFacts, a Seated Liberty half dollar of this type weighs 12.44 grams, measures 30.6mm in diameter, is struck in 90% silver, and has a reeded edge. A coin that doesn’t match these specifications—within normal wear tolerances—warrants further scrutiny before purchase.

Buying considerations

Certified versus raw coins

Given the coin’s rarity and the meaningful price gap between grades, certification from PCGS or NGC is strongly recommended, particularly for anything represented as Mint State.

Understanding grades

Most surviving examples show significant circulation wear. Because the total population is so small, even well-worn, problem-free examples hold real collector value—don’t dismiss a heavily circulated piece as unimportant.

Problem coins

Cleaning, retoning, and rim damage reduce both grade and desirability. A details-graded example can be a more attainable way to own the date, but understand the specific problem before buying.

Authentication and seller information

Confirm that both the mint mark and the absence of the motto are clearly visible in listing photographs, and that any certification number is verifiable directly with the grading service.

Suggested search terms and filters

Try “1866-S No Motto half dollar,” “1866-S Seated Liberty half dollar no motto,” or “1866-S 50C no motto.” Narrow by grade or certification service.

Availability and pricing notes

Genuine examples are scarce and don’t turn up often. When they do, compare grade and certification carefully—given how few Mint State examples exist, even small grade differences can carry significant price differences.

Frequently asked questions

Why does an 1866-S half dollar without the motto exist?

New dies bearing “IN GOD WE TRUST” weren’t shipped to San Francisco until March 1866, so the Mint kept using its old No Motto dies for a short period before the new dies arrived.

How rare is the 1866-S No Motto half dollar?

PCGS reports roughly 30 known across all grades, with only about four in Mint State (MS-60 or better) and the finest known around MS-65.

How do I tell it apart from the 1866-S With Motto half dollar?

Check the reverse above the eagle. The No Motto version lacks the “IN GOD WE TRUST” ribbon that appears on the With Motto version struck later that same year.

Is this coin valuable even in low grades?

Yes. Because the total surviving population is so small, even heavily circulated, problem-free examples hold meaningful collector value.

What if no suitable coin is currently available?

Add “1866-S No Motto half dollar” to your wishlist to get notified when matching dealer inventory appears.
