I found a 1976 10 pesos coin from mexico while roll searching halfs.
It only weighs 9.88 grams as opposed to the normal 13.96 grams and its almost half the thickness of a normal 10 pesos coin- its a little over 1mm thick and it should be 2.30mm thick.
These are cupro-nickel, would wear and tear etc reduce this coin in size this great?
* I compared it with a 1979 10 pesos coin I also found.*
I know next to nothing about foreign coins, any info on this is appreciated.
