Tibet Sho - date identification assist

[CameronK]

Hi;

I'm having some trouble dating this coin. Can someone assist? I can read the '16' lower right but I'm having trouble with the other number (16-xx). I thought it was 80 but that doesn't seem to make sense.

Thank you for the review. The coin is 24mm, 5.0g

I should say: 1 sho, rabjyung 16 lo 2 = 1928.

Thank you! I was looking in the wrong area.
