Value of coin when Krause rates it only as rare

I bought this coin in uncirculated condition on ebay from a coin dealer. What would be the value of the coin when Krause just lists it as rare with no values? Yes it is the silver coin.

The value would be, what ever the market will bear.

Raw, it's worth very little, because no one will believe it's real. If you get it authenticated, by a reputable TPG, then it's probably worth $5-10,000. I base that estimate on what other rare coins from Thailand have sold for on Heritage.

You can email HA directly and they will give you an estimate. It can take anything up to several weeks for a reply but they have always given me a satisfactory reponse.
