Russian wire money

Dear all,

Can I ask for your wisdom in identifying these coins? I know the last two are probably unidentifiable, but I thought I'd include them anyway. The weight is around 0.22-0.33g and the dimensions around 7/11mm.
I am truly very grateful for your input.

Hello

1-6 - Peter I
​​​​
7-8 - do they copper or silver?

1 - 6: Russia - Peter I the Great / Ivan V (1682-1696)
You can find it here: Numista Database
You can read about these rulers on wikipedia.org.
This is one example, where two monarchs were ruling at the same time... Very interesting...

Also HERE is the list of all possible variations of the above coins...

7-8: sorry can't see anything on them...

1-6: Peter I the Great
7: probably Alexey Mikhailovich, "Copper Riot" kopek
8: too far gone to identify, though likely same as 7

I don't think any of them could be attributed well enough to get a specific Numista entry - or, rather, perhaps they could, but that would take hours of careful checking; the Numista representation of Russian wire money is based on the Kleshchinov-Grishin catalog, which is extremely granular for those areas in particular (both Copper Riot and Peter I coins were issued in literally hundreds of minor variations, all of which have their own KG numbers, and the condition of typically available specimens is pretty bad).

1-6: Peter I for sure
7 and 8 look copper. Probably from the time of the "copper riots".
