Some Mexican Coins

The 1970 5 centavo is KM-427 an 18mm Brass coin. There was a mintage of just over 163 million copies and it has been demonetized - so it is no longer current. It is worth less than a dollar as an MS63.

The 1988 5000 Peso coin is the KM-531 which is a copper-nickel commemorative of the 50th Anniversary of the Nationalization of the Oil Industry. The mintage was 50 million. The coin has a book value between $4 and $12.

The 1989 1000 peso coin is the KM-536. It is an Aluminum-bronze coin with a mintage exceeding 200 million. Book values run from under a dollar in VF to about $5 in high MS grades.

The 1992 5 Peso was made after the monetary reform. It is the first issue of the bi-metalic ring coins now in use in Mexico. It is a KM-552 and has a stainless steel ring with an aluminum bronze center. This type was issued for 4 years only. It is almost identical to the KM-605 issued after 1996 - the only difference is the N before the denomination on your coin which indicates New Pesos. That coin is still current so in Mexico it has a face value. But they still turn up junk coin boxes here in NC for 50 cents or less in VF to EF condition.
