Melt value is a floor, not a price. A Diez Pesos (90%) in collectible grade, or a scarce date, can be worth well above its silver. Dealers also buy under melt and sell over it — the spread is how they make money, so expect to pay a premium buying and receive a discount selling.

Silver standards in Mexico
Mexican silver fineness stepped down repeatedly through the twentieth century, from 90% and 72% issues down to 50%, 30% and finally 10%, before silver left circulating coinage.
Denomination tells you very little here. The same peso face value spans 72% and 10% silver depending on the years, so the date does all the work.
