In 1905 a monetary reform was carried out in which the gold content of the peso was reduced by 49.36% and the silver coins were (with the exception of the 1-peso) reduced to token issues. Bronze 1  and 2 centavos, nickel 5 centavos, silver 10, 20, and 50 centavos and gold 5 and 10 pesos were issued.

In 1910, a new peso coin was issued, known as the ''Caballito''. The obverse had the Mexican official coat of arms (an eagle with a snake in its beak, standing on a cactus plant) and the legends "Estados Unidos Mexicanos" and "Un Peso".  The reverse showed a woman riding a horse, her hand lifted high in exhortation holding a torch, and the date. These were minted in .903 fineness silver from 1910 to 1914.

In 1947, a new issue of silver coins was struck, with the 50 centavo and 1 peso in .500 fineness and a new 5-peso coin in .900 fineness. A portrait of [[José María Morelos]] appeared on the 1 peso, with [[Cuauhtémoc]] appearing on the 5-peso; and this was to remain a feature of the 1 peso coin until its demise.  The silver content of this series was 5.4&nbsp;g to the peso. This was reduced to 4&nbsp;g in 1950, when .300 fineness 25 and 50 centavo, and 1 peso coins were minted alongside .720 fineness 5 pesos. A new portrait of Morelos appeared on the 1 peso, with Cuauhtemoc now on the 50 centavo and [[Miguel Hidalgo y Costilla|Miguel Hidalgo]] on the 5 peso coins. No reference was made to the silver content except on the 5 peso coin.  During this period 5 peso, and to a lesser extent, 10 peso coins were also used as vehicles for occasional commemorative strikings.<ref>{{cite web|url=http://cointypes.info/mexico/mex5p.htm|title=United Mexican States Coins: Type Collecting - Five Pesos|first=Ken|last=Polsson|website=cointypes.info|access-date=16 October 2017|archive-url=https://web.archive.org/web/20171017042514/http://cointypes.info/mexico/mex5p.htm|archive-date=17 October 2017|url-status=dead}}</ref>

[[File:Imm.jpg|thumb|right|upright=1.2|100 pesos of the old Mexican peso, 1988 (Series A).]]
Between 1960 and 1971, new coinage was introduced, consisting of brass 1 and 5 centavos, cupro-nickel 10, 25, and 50 centavos, 1, 5, and 10 pesos, and silver 25 pesos (only issued 1968 and 1972). In 1977, silver 100 pesos were issued for circulation. In 1980, smaller 5 peso coins were introduced alongside 20 pesos and (from 1982) 50-pesos in cupro-nickel. Between 1978 and 1982, the sizes of the coins for 20 centavos and above were reduced. [[Base metal]] 100, 200, 500, 1,000, and 5,000 peso coins were introduced between 1984 and 1988.
