As promised here are some scans from the recent small lot I won. I would imagine most of these are common, particularly the NY Central Railroad cancels. I've seen the HR Stevens cancels before but I don't know who they are or what they did though. The blue NY Gold Exchange cancel is interesting! The R54a hasn't a neat cancel and unfortunately has a crease. And the pair of R26c's has "hanging chads". What's with that?
Hi Southpaw, and thank you for that great exhibition! I just wanted to answer your note about the "hanging chads". I suppose you are talking about the "blind perforations"? That is where the perforator was either misadjusted or very dirty; the pins did not go all the way through the paper. Blind perforations are fairly common on stamps - even on modern ones!
