This is a Russian 3 kopeks, Y#11.2, mintage 9,467,000 it catalogs (in my 2009 Krause) as $3 (£1.87) in F, $5 (£3.12) in VF, $10 (£6.25) in XF and $20 (£12.51) in uncirculated. If I had to guess the grade, I'd say at least fine (unless there's some damage I can't see), so if the catalog's values are correct, this coin would be worth more than half the cost of the entire lot. That said, the values expressed in the catalog are rarely 100% accurate.
