Without seeing the reverse, I'd say KM#19, although the example here doesn't appear to have the date stamped where you've circled, or maybe it just isn't showing in the picture: https://en.numista.com/catalogue/pieces22258.html

I'm not an expert in any kind of coins, but I reckon I'm good at research and will do my best to help. Feel free to tell me my identifications/valuations/gradings are wrong. It's the only way I'll learn.
