The writing is not in the English alphabet. One side features a castle with three towers and a crest on top of it. The castle also has rays extending from it. The other side has a young man's face facing left and he is wearing a necklace and three medals. If it is any help, I don't think the symbols/lettering is an Asian language. Post if you have any idea what coin this could be - I have been searching all over the internet with no luck...
A Thai Bhat I do believe. So the characters are from an Asian language. Do some searches for Thai Bhat and see if you can ID the coin now.
