These chips come from a resort in Myanmar along the Khong river on the borders of Laos, Myanmar and Thailand in an area called Golden Triangle. The Paradise Resort has two small casinos in it. The currency used is Thai Baht. They also use a 25 baht chip at each place but they are very hard to come by if you do not play. I have three sets of the four chips shown available for $20 delivered in the USA I have a couple extras of the two fifty available for $8 for the pair delivered in the USA
