Russian Wire Coins... Anyone Good At Telling Year?

From top to bottom, denga (1/2 kopek) of Ivan IV (the Terrible) as Grand Prince (1533-1547), very worn kopek of Alexei Mikhailovich (1645-1676, IIRC), and another "late 1699" issue (same type as the second coin in the OP - this is now the third example I've seen of this supposedly rare type).
Ironically enough, none of them have a psi (at least, not in the date).

I'd say $3 is too much for the Alexei Mikhailovich kopek (even if it was in better condition), and probably about right for the other two, but I don't know much about the market outside my country.
