Russian Coin Identification

I did research and found out that it "Novgorodian of kopeck Ivan the Terrible, minted 1547-1584"

The coin is upside down.
Sorry, but I did not understand your second question.
The legend is indicated on the site, isn't it?

The inscription on your coin coincides with the data of the website. The fact is that the way to create these coins is quite primitive ( you can look at the photo below and see for yourself)
#1040;-ingot of silver

#1073;-rolling on the wire and cutting,

#1074;-flattening,

#1075; - stamps for manual coinage,

#1076;-ready-made coins " scales"



Therefore, on exactly the same type of coins, the letters may be misaligned, poorly minted, or missing.

Here's the legend:
Lettering:
#1062;#1056;#1068; #1048;
#1050;#1053;S#1068; #1042;
#1045;#1051;I#1050;I I#1042;
#1040;#1053;#1066; #1042;#1057;#1045;
I#1040; #1056;#1059;#1057;I

Translation: Tsar and Grand Prince Ivan of all Rus

Thank you all for your help
