Welcome to Stamp Community Forum, Chris!
I only took a quick cursory glance, but it appears...
-- there are no Finnish stamps, looks like all Russian
-- I really didn't see anything particularly valuable in there (again, cursory glance); which stamp/stamps did you consider valuable; almost all the stamps catalog for $1 or less, maybe a couple that catalog for slightly above $1
All the stamps appear to be post-1880, so are very common except for the higher denomination stamps (which I didn't see any in your pics).
Perhaps you (or a friend) thought they were the earlier issues, which are more valuable. But I did not see any pre-1880 Imperial Eagles in the pics. Sorry. Maybe someone else will spot something.
