Can some one help me identify this coin.

i have searched for a long time and just can’t find where this comes from.

thank you.

Have a look under Thailand you will find your coin there.

download the app coinoscope on your smartphone its particularly good with identifying coins.

I think it is this one:

You folk are all awesome
thank you, thank you, thank you.

If a member has a coin with unreadable lettering, there is 'Numisdoc' near top right.
In it are five sections, the second of which is 'Dates & calendars' - so look at each of
the seven Calendars to see if anything matches.
