That does look similar, but the "3" and the "7" look like either a Tibetan "3" and "1" or an Eastern Arabic "3" and "8". The problem is I think in Morocco they use the backwards 7 instead of the almost-3 to indicate "3", so I'm thinking it's more likely Tibetan.
Oh, I should add -- the note with the coin said it was purchased in Kathmandu in 1969. The note has Nepal written then crossed out, and then Tibet written in with a question mark.
It's probably a temple token or some such.... Nepal uses a crescent and sun on their coins as seen in two segments of the star, and the 3 looking thing in the center is probably 'Aum'
