It's a 5 Baht coin from Thailand, this style was issued between 1988 and 2008 (your coin should have a date but I'm not good at reading Thai dates). Not a rare or valuable coin. If you go to Thailand, you might be able to spend it for face value (about 15 cents US).
Numista is a great place to find information, if you know the country. https://en.numista.com/catalogue/pieces1640.html If you deal with unknown World coins very often, and have a smart phone, you should download Coinscope. Easy to use and fairly correct.
There are two 5 baht coins that are worth more than 5 baht because of the mintage but I would have to see a real good closeup of the reverse to see what the date is.
