Am I Not a Woman & A Sister. [Belville, NJ]: [Gibbs, Gardner & Company], 1838. 

Diam. 27 mm copper token. Obverse with a kneeling woman in chains with legend "Am I not a Woman & a Sister." Reverse shows a laurel wreath inscribed "Liberty" and "183[8]" at center with "United States of America" at perimeter. 

An abolitionist token commissioned by the American Anti-Slavery Society to commemorate the formation of the Liberty Party. The original design with a man was commissioned by the Committee for the Abolition of the Slave Trade which was formed in 1787. The design first appeared in print in the March 1788 issue of The Gentleman's Magazine and Josiah Wedgwood produced jasperware cameos in the late 1780s. The first numismatic instance was circa 1794 with a reverse legend reading "Whatsoever ye would that men should do unto you, do you even so to them." The design featuring a woman and feminized slogan was first used by the Ladies Negro's Friend Society, established in Birmingham, England in 1826, which distributed abolitionist pamphlets employing the design. 

An advertisement in the 27 November 1837 issue of The Emancipator announced the token, noting that a counterpart male figure token would be issued. This coin, however, was never struck as the US Mint Director suppressed the circulation of the coin shortly thereafter.
