I am assuming that marks on the two Scott's #45 are cancellations. However, my doubt comes from having a #38 with a very similar mark on it. Were those the standard cancellations for Russia back then?
Also, the second #45 appears to be an imperf (due to the white border lines being intact.)
If that is so might there be a different valuation for it? Scott's has a HUGE difference for an imperf pair but says nothing about a single imperf. I'm guessing it's because it has the same value as the perf.
Note: I know that if there is a difference in valuations it will most likely be irrelevant in this case due given how uneven the borders are. However, I can use the response to be evaluate other stamps that might fit this situation.
Any experts out there that can answer these two questions?
Thanks!
