Identifying a Polish Lithuanian Silver Coin [επιλυμένο]

I have other coins like this one but i cannot seem to find this exact same coin here if any information would be very helpful . 

For example i found these 2 coins 

N#126824

N#126828

Mine does not seem to have a date on the left top side like the others in the link and also as i see it says ( POLO ) on the bottom left . 

Diameter 19 mm  and weight 0.8 grams 

Thank you

Why not Bydgoszcz 1624 as in the photo in your second link?

I am pretty sure we can see the top of the 2 and the 4 in the date.
