Early Serbian Dinar, Venetian Grosso, or remakes? [solved]

1. 19mm diameter, .5mm thickness, 1.8g


2. 21mm diameter, .75mm thickness, 2.1g

Have a pretty fair idea but not certain what these are. From the appearance and measurements Venetian Grosso or Serbian Dinar from the 13th or 14th century. I'm also wondering if they're genuine or 20th century remakes judging by the coloring of the silver. They are not magnetic but the weights and measurements are similar. The lettering to the right I'm able to find but not match the lettering on the left.

I posted this about 8 years ago (http://www.worldofcoins.eu/forum/index.php?topic=26869.0)...

Venetian grosso , aside from the legends, have DVX under the banner (dux for 'leader' or doge)

@Creole, I am pretty sure the first one is Pietro Gradenigo: https://en.numista.com/catalogue/pieces113607.html

Even though we cannot see all of the letters on the left, we can at least count them, and I am pretty sure the 4th and 5th letters are R A.

Uncleaned examples of these coins often have a dark gray patina. The patina on yours looks very uniform, which is a bit suspicious, but the details look authentic to me.

Maybe someone else has an idea on this?

Thank you all for your time and help. I started looking a little more carefully at the Venitian Grosso coins to find a comparison and with half the name cut off I also thought maybe Pietro Gradonigo or perhaps Bartolomeo Gradonigo when comparing all of them. Something seemed strange about the feel of it is why I wondered if it was contemporary. Had no info when I bought it. I got it for hardly anything out of a lot.
