City of Riga coin question, can you check yours? [επιλυμένο]

Hello experts!

So I have the coin of the left.

The coin from the right is from the numista catalog: (https://en.numista.com/catalogue/pieces31474.html)



I noticed mine have only one circle around the GA when the numista and krause have 2 Circles, and other minor variations but I think is ok.

I see there are lots of types of legends, but my question is, it is normal to have only one circle around the GA?

I ask this because googling online, most of the pictures of this coin show only one circle.

Now I am not sure if mine is fake or just a variation.

What you experts think? Can you check your coins and see if they have one or two circles?

Thank you

Maybe someone with the referenced catalogs on the numista website could check that. Couldnt find online.

Hello,

Coins from 1621-1626 have 2 circles, post-1626 - one (with some exceptions)

Possibly because the post-1626 have lower silver content (4% less) and it was made to make easier carve out more valuable coins from circulation
