Coin from Mexico with Japanese chopmarks

Hello expert

Is there an expert member who can tell me the right story about this coin?
I think this coin is from Mexico, type KM#377.12, 8 reales, material S, round 38.5 mm, thick 2.5 mm, weight 27.05 gr, density 10.34. Is this the right number??
Are the chopmarks Japanese? Are this the right chopmarks?? There is a detail picture of the center chopmark. What is the market value and where can I find this type in the database of munista.



thanks for help

Big standardized silver coins such as this were used all over east Asia as trade coinage.
There are also officially sanctioned 8 Reales coins from Japan but there are more faked coins and counterstamps than real ones and they go for many 1000s of dollars.

if a coin is valuable, they are copied by the chinese, even made in silver.

True there are loads of fakes, however I would say this might be really deal just from a picture of this coin, however would be NON-gradable that is with the chop (there is actually more than one on this coin) and test mark, it would be marked with surface has been alternated.

Note it wasn't uncommon for 8 reales to be used as trade silver in Asian.
