The Sun Stone Connection
The outer ring carries the Anillo del Resplandor. Its stylised ornament frames a clear $1, selecting one part of the Sun Stone for a modern monetary object.

A Symbol from the Sun Stone
Everyday Money. A Timeless Heritage.
A silver-coloured ring, a warm centre and a bold numeral: the 1-peso coin pairs everyday value with the Sun Stone’s Ring of Splendour. Since 1993, its notation and core material have changed within one continuing monetary unit. Read a familiar object through its design, history and materials.

N$1 becomes $1 in 1996; the monetary unit continues. A bronze-coated steel core follows in December 2025. Inscription and material are separate chapters.

One peso is 100 centavos. The C design is in the current catalogue, and older N$1 coins remain valid. Official status does not measure their frequency in change.

The details behind the design
Identity, history and materials—read together.
01
The Sun Stone Connection
The reverse does not reproduce the entire Sun Stone. Its large $1 occupies the centre, while the outer ornament is the Anillo del Resplandor, named in the original decree. Reading the border and the denomination together reveals the balance between a clear monetary sign and a historical visual source.
02
Design Through Time
The B coin uses N$1; the C coin uses $1. Removing the N in 1996 changed the notation, not the value of the monetary unit. Banco de México reports bronze-coated steel cores from December 2025. A change of material is not evidence of a new denomination or a new Sun Stone motif.
03
In Daily Life
A 1-peso coin represents 100 centavos. The C design appears in Banco de México’s current coin catalogue, while the older N$1 remains among valid designs. A catalogue entry establishes official status; it does not tell us how often a particular date appears in change.
04
One Unit, Two Inscriptions
The reform took effect on 1 January 1993: one new peso equalled 1,000 preceding pesos. The word nuevo and the N prefix made the distinction visible during the transition. The later removal of N did not repeat that conversion. A 1993 N$1 and a later $1 therefore belong to the same modern monetary system.
05
Read the Coin, Face by Face
On the obverse, the national arms sit beneath ESTADOS UNIDOS MEXICANOS. On the reverse, locate the date above the numeral and the Mexican Mint’s M° mark beside it. These visible details describe the photographed example; they do not establish its alloy by colour alone. The 2019 example shown here illustrates the C design.
06
A Material Era, Carefully Dated
The original specification combines a stainless-steel outer ring with an aluminium-bronze centre and a nominal total mass of 3.95 g. The July 2024 resolution permitted the selected replacement core to be manufactured from fiscal 2025 after technical adjustments. The issuer’s December 2025 implementation statement is more specific than that permission year. The precise selected new-core total mass is not established here.
07
Compare What the Evidence Can Show
Start with denomination, inscription, diameter and the named reverse motif. Record a specimen’s date separately from the first release of its design. The photographs are design references, not a claim that both faces are documented views of one specimen. Complete annual mintages, scarcity rankings and market prices are not established by the sources used here.
