Steve, do your database images include any of the straight type PB? Are they all high grade?
Good luck to BKB on the auction..

perhaps with coin in hand, we will have an answer. Indeed, fun to discuss!
I have a wide variety of grades, and I'm sure I have a whole lot more images of this coin waiting to be processed (I have a sizeable backlog).
As far as relative scarcity of the types:
I see 2 distinct positions for the PB
I - PB extended 50% out from the tail feathers.
II - PB 'tucked in' with the bottom of the letters flush with the bottom of the tail feathers.
The count is
TYPE I - 17 coins
TYPE II - 2 coins
so a ratio of 8:1 (albeit with limited statistics).
The eBay piece is TYPE I. The Squirrel coin and Molotok example are Type II
Including those we get a ratio of 18:4, or about 4:1, as per BKB.
Steve
