what condition are considered bottom stamps (2x green and 1x black) in the first picture? Thank you.
For the 3 ruble stamp, its upper right corner is rounded off and so is considered faulty, reducing its value quite a bit -- collectors are picky. You can still collect it. If you mean the 10 kopeck stamp above it, that's not a postage stamp but a fiscal/revenue one, and very faulty.
The 1 ruble green stamps look just fine from what can be seen. Be warned than tiny tears, stains and paper thins on the back also reduce stamp value a fair amount.
