Surfaces look too even in color, and pattern is very mushy. Probably fake. Here is a page about genuine ones:
Are they fake?
The 1743 looks real. If it is a full rouble, it should weigh 25.5 grams.

This is the one.
Cast typical russian fake. grainy surface. Everything looks to have same wear . Hair should look separated . Burnt my fingers too many times with these coins :)
Thank you. Already sent them back. Looks like they are coming from our "friends" in China and they never seen Russia. :)
