Russia-Empire:
number 2 and 4 - denga (1/2 kopeck) of tsar Ivan IV (1535-1584), both seem to be issued before 1547
number 3 - kopeck of tsar Michail Fedorovitch (1613-1645)

​Just to be on a safe side - can you weight your number 2 and 4?

​Hello
Thank you for your interest, I can not weigh below 1g today.
The former coin owner also responded to the call and sent a specific incorporation:

2,Kopeck - Ivan IV (don't know the exact type, but probably this one https://en.numista.com/catalogue/pieces111782.html)

3,Kopeck - Mikhail I (probably this one https://en.numista.com/catalogue/pieces17466.html)

4, denga of Ivan IV (probably this one https://en.numista.com/catalogue/pieces111603.html)

Thank you Ivan

​
​4, denga of Ivan IV (probably this one https://en.numista.com/catalogue/pieces111603.html)
​

​number 2 - if the weight is 0.6 g or a bit more than yes, it is a kopek (not denga) and we don't have this type in Numista catalog yet
number 3 - yes, kopek of Mikhail I (aka Mikhail Fedorovitch) but the coins is heavily corroded to say which type it belong to
number 4 - depends on the weight, could be denga (0.3 g) or kopek (0.6 g)

​Hello
Thank you glycan
My scales are at work I'm waiting for a medical operation as soon as I can consider it and if I do not do a lot of doing that
cook your teas for chilly days

Ivan,
Feel better soon - "Bonne santé!" as French people say - and we'll continue the discussion when you are ready.
