The state of Sinaloa issued only one series known as the "Liberty Head", which has on the obverse a small head of liberty within a laurel wreath. The legend around "ESTADO LIBRE Y SOBERANO DE SINALOA". The reverse has within branches of laurel and oak, the denomination "1/4 DE REAL", the date with reeded edges. These were issued in 1847, 1848, 1859, and 1861 through 1866.

The legislation for division of Occidente was passed in January 1830. The approval of the decree of division creating the states of Sinaloa and Sonora was issued on 13 October 1830. Under the National Government supreme decree of 1847 by the Departmental Council, state electors were allowed to choose a legislature and governor.

The first issue of Sinaloa cuartillas was ordered on 2 March of the same year (30,000 pesos or 960,000 cuartillas)Pradeau, op. cit..

The 1861 cuartillas were also produced at the Hermosillo mint.

A common error of the 1862 cuartilla is the result of a slightly filled or irregular die resulting in BEAL rather than REAL.

Some of the 1864 issue was possibly struck in San Francisco and smuggled into Mexico at the instigation of Fortunato de la Vega, the lessee of the Culiacan mint. The national government became aware of this and threatened prosecution of those involved.

Additional coins dated 1859 were restruck in 1872 with the authority of the governor, Eustaquio Buelna[text needed]. Likewise, he had more 1859 dated copper struck in the Alamos mint, all without the approval of the state legislature or federal authorities. The 1859 dated cuartillas are found with and without dots after the date; the significance of this is not yet known.

1861/9There has been some debate over the 1861 over 9 which some say is an 1861/0. We can say with certainty that the first one in the date has been repunched and the 6 lacks any trace of over striking. The small dot under the final digit is not consistent with most 1859 coins. dot at date

A pattem cuartilla was produced in 1861 with a larger Liberty head. It has the standard legends plus the initials QD under the bust for Quintín Douglas, an American who was a mint employee at this time.


On 30 December 1870 Sinaloa decreed[text needed] copper coin to be amortized, which was to be financed by various new taxes.
