The humble bronze centavo — a 44-year workhorse type that survived revolution, reform, and redenomination.

History

The bronze 1 centavo of KM 415 was struck from 1905 to 1949 at the Mexico City mint — a 45-year workhorse of small change (Greysheet; coinvarieties.com, accessed 2026-09-16).
Specifications: 3 g, 20 mm, bronze, plain edge (coinvarieties.com, accessed 2026-09-16).
The obverse carries the national arms; the reverse shows a large ‘1¢’ within a wreath, with the date and ‘Mo’ mintmark (heritcoin.com, accessed 2026-09-16).
Mintage for 1943 was 4,310,000 (heritcoin.com, accessed 2026-09-16).
As a low-denomination bronze coin of the 1940s, most survivors are worn; full-red uncirculated examples are the condition prize (heritcoin.com, accessed 2026-09-16).

Key dates and varieties

1943 — 4,310,000 struck, a mid-series wartime date (heritcoin.com, accessed 2026-09-16).
The type ran 1905–1949, so date collectors chase the full run rather than a single key (Greysheet, accessed 2026-09-16).
Choice Uncirculated — the 1943 in full mint red is the condition target for this bronze issue (heritcoin.com, accessed 2026-09-16).

Collector notes

Bronze has no silver value — buy on grade and eye appeal, never on melt hopes.
Look for original mint red; cleaned bronze retones dull and loses value.
Date and mintmark sit in the reverse wreath — make sure both are fully struck before paying a premium.
Cheap enough to collect the whole 1905–1949 run — a satisfying short set.
