Thailand coin

Found this on the hall floor a day or two after Terry had been insulating the gas meter cupboard. We think it must have been at the back. It's a Thai coin, 5 baht, minted between 1988 and 2008. We moved in here so it seems likely that it would have been here before we moved in (1998) as we've never been to Thailand.
Extra of the other side of the coin.
It's rained all day today so there is little ice left now. The rain was a bit sleety at times.
