My first guess is Thailand, then maybe Burma (Myanmar) or Nepal. Value is probably not much. It appears to be made of Cupro-Nickel. When posting photos of coins, please post a pic of both front and back. Every little bit of info helps with identification.
Thailand is right, I think, and the date should be on the left. 2561 (Buddhist calendar) = 2018. The digit "1" (five o'clock position) means that this is a 1 baht coin. So it is one of the coins featuring the new king, see here for example. As for the value - as @Hookman wrote, not much ... Christian
