chicome tomin (Osu10v)

There were coins for a peso, a half peso (tostón), two reales, one real (a tomin), a half tomin (called a medio in Spanish and often a melio in Nahuatl) and a quarter tomin (cuarto). And coins could be found in gold, silver, or even copper. See: a publication by an auctioneer of old coins found in shipwrecks, https://www.sedwickcoins.com/articles/shipwreck_intro.htm.
For additional tomines that appear in this Visual Lexicon collection, see below. Sometimes the number four will be turned sideways or even upside down. For an image of four pesos plus six tomines, see our Mapas Project detail, https://mapas.wired-humanities.org/tribcoy/elements/tribcoya/10. And here are two pesos and five tomines: https://mapas.wired-humanities.org/tribcoy/elements/tribcoyb/60. In all these cases we are NOT seeing a circle for each of the coins, but rather glyphs that are marked to give a sense of the number of coins involved. Tomines and melios were far more common in the hands of Nahuas in this period than pesos, which were worth so much more. In our Online Nahuatl Dictionary, we have attestations of references to tostones (half pesos) in Nahuatl manuscripts from the sixteenth and seventeenth centuries.
