Sir or Madam -- A 1942 Mexican 5 centavos is a *good date* for the series if your coin looks like the one in our picture. There is another 1942-dated 5 centavos that looks different (it has a big '5') which is not worth very much. This page deals with coins that look like the picture on the left. Here is a listing of typical catalog values for all dates except 1942, followed by the 1942 listing.
CINCO CENTAVOS 1943 to 1955:
worn: less than $1 US dollar approximate catalog value
average circulated: $1
well preserved: $2
fully uncirculated: $5
coins dated 1952 and 1955 are worth about three times these amounts.
CINCO CENTAVOS 1942:
worn: $10 US dollar approximate catalog value
average circulated: $25
well preserved: $100
fully uncirculated: $500
