Suspicious coin [resuelto]

Hi! So, I found this Siamese coin and it looks extremely suspicious. What do you all think?

Weight is 18.5 grams and it is fairly large.

Personally I think this looks more like a token than a coin, because of the lack of writing, clear date and denomination. Here are a couple of descriptions online, one of which is ambiguous about whether it's a coin or token. Hopefully another member will be able to clarify this.

No, I checked, but, Siamese coins in that time period don’t have writing. Thanks anyways.

What’s the diameter? 

Definently a copy of one of these;

N#15252 

N#15285 

As a point of interest I have an early example on zeno of this type that later types were based on, it is lower weight than yours so different denomination and design, mine is made of a Tin alloy and cast, 

Weight, g: 7.65

Size, mm: 31

Denomination: 1/16th fuang

Metal: Tin

Somdet Phra Paramin Maha Chulalongkorn, 1868 - 1910,
(renamed in 1910 Rama V, as his official name),
mint: Grand Palace, Bangkok,
cast(plain edges) in the first year of reign, 1868,
The type is undated.
Above the elephant is the value in Siamese, below in Chinese.

The rim and the other more detailed bits look like they are too close together. Also, the diameter is around 38.8 millimetres with the thickness being 2.1 millimeters.

But then again, even if so, it’s actually a very nice copy if I do so say myself. The price was 200 baht.

So, I can conclude it was fake?

What do you think? 200 baht is a bit more than 5 €. You know what they say, when it's to good to be true it mostly isn't.

I knew the risks involved and I definitely knew they were bound to be fake… but, alas, the other risk-loving part of me said: “DO IT. IT MIGHT BE A PATTERN COIN OR A REALLY NICE DEAL.” So, as you can see, a bad decision I don't regret. Thanks anyways, @Essor Prof .
