Wrong size/weight for Gold 1882 Peso. Is this fake?

Hello everyone. I came upon this 1882 1 peso, gold. However, the size and weight are different from those mentioned in catalogues. Instead of 1.7g it has 0.58, and the diameter is 10mm instead of 14mm. Is this a fake? What is the point in making it obvious then?

also, the marking reads M .875 Mo

Perhaps you should contact a jeweler to do a test

I came across these "coins" few years ago. It is a serie of gold plated replicas.
They are all 10 mm and underweight, someone call them hge gold (heavy gold electroplated).
Look following this track.

It may be a Mexican wedding token.

​Thanks, this could be it. it also reads PIA very small on the reverse.. but most likely it is the case of a replica. any idea what value it might have?
