1866 Seated Liberty Quarter (Motto)

The 1866 quarter marks the first appearance of the motto "IN GOD WE TRUST" on the denomination, added on a ribbon above the eagle on the reverse. This change opened the final and longest-running subtype of the Seated Liberty quarter series, which continued with the motto through the design's retirement in 1891.

Beyond its significance as a design milestone, the 1866 Philadelphia business-strike issue is notable for a very small mintage, making it one of the true key dates of the With Motto Seated Liberty quarter series and a priority target for collectors pursuing a complete date run.

During the Civil War era, rising religious sentiment and public pressure led Congress to authorize the addition of the motto "IN GOD WE TRUST" to United States coinage, beginning with the two-cent piece in 1864 and expanding to other silver and gold denominations over the following years. The quarter dollar received the motto starting in 1866.

The change was implemented by adding a ribbon bearing the motto above the eagle on the reverse, otherwise leaving the Seated Liberty design largely unchanged from the No Motto type used since 1838 (with the drapery addition of 1840 and the brief Arrows and Rays modification of 1853-1855).

Production of the new With Motto quarters at Philadelphia in 1866 was unusually limited, for reasons not fully documented but consistent with modest demand for quarters relative to other denominations that year.

The obverse continues the familiar Seated Liberty design: Liberty seated on a rock, holding a shield and a pole topped by a liberty cap, with stars around the border and the date 1866 below.

The reverse is distinguished from earlier Seated Liberty quarters by the addition of a ribbon reading IN GOD WE TRUST directly above the eagle, in addition to the standard UNITED STATES OF AMERICA around the border and QUARTER DOL. below. The eagle itself, with its shield, olive branch, and arrows, is unchanged from the No Motto type.

As 1866 quarters were struck only at Philadelphia, there is no mintmark. Collectors distinguish the genuine 1866 from more common With Motto dates primarily by its low survival rate and the correspondingly higher asking prices even for well-worn pieces.

With a mintage reported at well under twenty thousand business-strike pieces, the 1866 quarter is a genuine key date of the With Motto Seated Liberty series. Even heavily worn, problem-free examples command strong premiums compared to more common dates in the run, typically reaching well into four figures.

Choice circulated or mint-state examples are considerably rarer still and can command prices well into five figures, reflecting both the coin's low original mintage and its importance as the debut year of the motto on this denomination.
