Modern Bhutan Half Rupee

Hello.

Dear colleagues, please help to identify this coin.
Is it KM 26 or KM 28.2? What is the difference? how to tell? weight is 5.9 g

Thank you

Please include links to the Numista entries when you post. If you don't you create extra work for people who want to help you.

In this case:

KM# 26: https://en.numista.com/catalogue/pieces30856.html
KM# 28: https://en.numista.com/catalogue/pieces9170.html

Your coin isn't KM# 28.2, that type is lighter.
