nauhtomin (Osu18r)
This painted simplex Nahuatl hieroglyph for a coin (tomin, a loanword) shows a blue coin (likely made of silver) with four white dots. If it had one dot, it would be worth one tomin, but with four dots it represents four tomines (nauhtomin, as combined in the gloss in the Codice Chavero, below), which is the equivalent of four reales (four eighths of a Spanish peso) or half a peso. The contextualizing image also shows a tomin hieroglyph with two dots, representing two reales or a quarter of a peso. The seven red circles have lines connecting them to the four-real coin. The lines imply a multiplier effect, or, seven times four, for a subtotal of 28 tomines. But then, off by itself is one more blue coin worth two tomines. Because there is no connecting line to this latter coin, it would just be added to the subtotal, bringing the grand total to 30 tomines. Humble Nahuas more often dealt in tomines than in pesos, given that a day’s labor on a neighboring estate might be one tomin. But elite Nahuas and Spaniards would be tempted to figure the total in pesos, dividing by 8, resulting in 3 pesos and 6 reales.

While there is no Nahuatl-language gloss to explain that tomin is the vocabulary term of focus or that nauhtomin can refer to four tomines, but other material in this collection that includes coins makes these assessments reliable. The contextualizing image shows that twelve loads of “yerva” (hierba, grass, which is also called mazatlacualli, “deer” food, i.e. horse fodder, elsewhere in this manuscript) had this value, a little more than 3 and a half pesos. This was expected as part of the tribute in kind that the town would have to provide per day, according to the Spanish-language text on the manuscript page. Not shown here, this larger context includes a large number of peso coins in the top, center and left, which indicate the annual value of this tribute. The peso coins are also blue, but the peso of full value has a cross on it. At the bottom of the contextual image, a fully-clothed Spaniard named Doctor Villalobos sits in a curule chair, wears a sword, carries a staff of office, and emits a speech scroll from his mouth. These are all signs of his ethnicity and his status. Interestingly, the tlacuilo who painted this scene gives Dr. Villalobos, a judge of the high court (Audiencia) of New Spain, a hieroglyphic name that is a challenge to decipher. See a discussion of this challenge on the Tlacuilolli blog.
The visual representation of four tomines (the equivalent of four reales, or half a peso) will perhaps more often be found as a coin with the number “4” written on it. See an example from the Codex Chavero and another one from the Codex Osuna, below. But four dots would have been understood easily, too.
