Coin of Guatamala, Fake or not??

Hello expert

I found the coin KM#75 in my collection of Guatamala.
It is ultra rare in your database. It is 1 reaal, material S, round 20.2 – 20.5 mm, thick 1.6 mm, weight 3.92 gr. Year 1829 NG M
IS IT FAKE OR NOT, what is in both cases the value.


thanks for help

This coin is indeed rare, this is why there are not many info about this coin. Less than 30 confirmed surviving specimens are known and even fewer has been ever certified. Just from the picture it's pretty hard to say if it's a real one or a fake. The weight should be 4.4 g and there is a weak strike in year at number 9 but this does not necessarily mean that it is not authentic. Also you should know that this coin is different from other provincial coins from Central American Republic where the fineness of the coins is 0.903, this one has a fineness of .750. If it's a genuine coin in this condition probably it worth around 1500$.

Genuine? I do not know.
What is the hitory, provenance of this coin?
In my opinion,wihtout looking at the pictures, I would say it is a replica/forgery
But looking at the pictures, it looks real
There are some details that differ with other pictures.
It is worn, so the weight can be ok.
