cempohualli pesos (Chav1)
This simplex glyph stands for twenty pesos (cempohualli pesos), as the gloss and the contextualizing image show. The word "pesos" is a loanword taken into Nahuatl from Spanish. The peso is round and dark, and in front of it is what appears to be an ear of corn. Compare this sign with the one for fifteen from the same codex (also in the contextualizing image, below).

The reference is to the number of pesos, and corn is not literally present. The association between corn cobs and the number twenty is a cultural one. Twenty is a "full count" in the vigesimal system, and twenty ears of corn was probably a customary grouping.
