Ceres
The next series appeared in 1871 and 1872, and borrowed the contemporaneous designs of France, with profiles of Ceres and Emperor Napoleon III. While some of the nine values can be distinguished from the French stamps by color or value, others are extremely difficult to identify.
Several of an additional series of Ceres heads issued between 1872 and 1877 have a similar problem, and are distinguishable only by being imperforate, as was the Colonies part of the Peace and Commerce issue of 1877 to 1880.
In 1881, a new series, featuring "Commerce" alone and inscribed "COLONIES", was issued for the Colonies, perforated 14x13.5. The 13 values, ranging from 1c to 1fr, were in colors comparable to those used for France. In 1886 the 25c stamp, previously printed in yellow, was reissued in black on a rose-colored paper. Stocks of the Commerce issue were frequently overprinted by the colonies during the 1880s and 1890s.
