The first 159 gram weight appears to be a standing hintha.

I believe that the second 159 gram weight is a Karaweik.

I would be grateful for opinions as to type, whether genuine or fake, and estimated age.

Thanks in advance for your assessments.

Hi Peter,
I don't repeat my statement of nomenclature ...

right: Karaweik (K1), 10 Tical, early 19th century, genuine.
