THE SHORT ANSWER
A displayed date is observable; a production-year claim needs separate evidence
Separate Banco de Mexico's confirmed 1921, 1931 and 1943 production history from seller date, restrike and rarity claims.
OFFICIAL TIMELINE
Three confirmed milestones are safer than a copied date list
Created as a circulating coin commemorating the first centenary of Mexican independence.
Banco de Mexico explicitly identifies the interruption.
The central bank attributes the return to growing demand for gold coins.
FOUR DIFFERENT DATES
Displayed date, production date, sale date and observation date must stay separate
Displayed date
The date visible on the piece.
Production date
Requires issue or manufacturing evidence.
Sale date
When ownership and money changed hands.
Observation date
When gold and market references were captured.
RESTRIKE CLAIM
Do not turn the 1947 date into an automatic production-year conclusion
A seller may use "restrike" for later-made pieces bearing an earlier displayed date. GoldObserve does not publish a universal date-to-production table because the official sources reviewed here do not establish one for every individual coin. Record the claim, source, evidence and pricing consequence separately.
CLAIM LEDGER
Grade the evidence before paying for a date story
| Claim | What can be observed | Additional evidence required | Safe conclusion |
|---|---|---|---|
| Displayed date | Legible date on the coin | Clear photographs and inspection record | The piece displays that date |
| Production year | Not established by appearance alone | Issue, manufacturing or authoritative catalog evidence | State only the documented production evidence |
| Restrike | A seller or grader may apply the term | Definition, attribution basis and durable record | Attribute the claim; do not convert it into a universal date table |
| Rarity premium | One asking price is observable | Matched transactions and a credible exit market | A premium is market evidence, not an official product fact |
AGGREGATE DATA LIMIT
Quarterly circulation is not the same thing as date mintage
Banco de Mexico's SIE table reports quarterly pieces for fine-metal products. It can show that the official product family remains active, but it does not prove the date, strike year, rarity or provenance of a coin in hand. Never attach an aggregate quarter to an individual piece without a valid chain of evidence.
FREQUENTLY ASKED QUESTIONS
Mexican Centenario Dates and Restrikes Explained questions
When was the first Mexican Centenario struck?
Banco de Mexico says the 50-peso Centenario was first struck in 1921 to commemorate the first centenary of Mexican independence.
Was Centenario production continuous?
No. The official history says production stopped in 1931 and resumed in 1943 because demand for gold coins increased.
Does a 1947 date prove the coin was struck in 1947?
Not by itself. A displayed date is an observable feature; production year, restrike status and rarity need appropriate issue records and expert evidence.
Does Banco de Mexico publish current Centenario activity?
It publishes a quarterly fine-metals circulation series, but those aggregate observations are not individual coin certificates or a complete date-by-date mintage archive.
