pantli.

Visually, the tecpantli in Nahuatl hieroglyphs is a flag or banner, but should be seen as a number or a reference to a row, line, etc., of things that are counted. As Gordon Whittaker explains (Deciphering Aztec Hieroglyphs (2021), this flag is not to be confused with panitl, or pamitl (in Tetzcoco), and never simply pantli.

yey pātli = three measures called "pantli" — Lockhart felt that the coefficient of three suggested that a pantli was a "set unit" (Tulancingo, September 9, 1657)

yn tlalli tlacopantl ypan icac cacahuatl (a parcel [measuring] half a pantli upon which stands cacao?); this sold for 4 pesos and 4 tomines or reales; it was sold by a humble indigenous person to a Spaniard; also attested is "tlahcopatli" (referring to half a pantli, apparently); this last one sold for 4 pesos and 4 tomines or reales; it was also sold by a humble indigenous person to a Spaniard; and we see "tlaltotl tlacopatl" (perhaps a small parcel, half a pantli); this sold for 6 pesos; it was also sold by a humble indigenous person to a Spaniard (Tulancingo, November 3, 1687 and October 7, 1687)
