Nano- Philatelic definitions are important. And, before I clarify the situation on the Pomeroy remainders, the first rule of philatelic scholarship is to assume that what you have is the most common variety, or item, until you find enough information to positively conclude otherwise. Scott's catalog rarely lists values for stamps that were not issued by the government or private entity that did the postal service. It is not an indication of value in such cases and generally, such stamps have little value.
On the Pomeroys stamps you have, almost all are not genuine stamps issued by Pomeroy. See a scan of the letter from the grandson of Pomeroy's printer's (Gavit) to noted philatelist George Sloane here:http://www.rfrajola.com/2k19/pomero...itletter.pdf
It basically states that the printer sold the "remainders" to Scott Stamp Company (in 1895 this happened). The Pomeroy stamps you have were from this immense hoard of printed stamps that were not issued. Scott apparently marked some "Reprint" - so these stamps, while not forgeries were never issued or intended to be issued by Pomeroy. Some past students, such as Henry Abt, believed that Gavit also sold the printing plate, and/or dies to Scott and that Scott printed even more.
Most of the other "stamps" on your scans were printed by Hussey and company for sale to collectors. So, even though some may have been printed from original plates, they were not done by order of the original proprietor of the post. These have little, if any, value. They were simply produced to satisfy collector needs.
Your "C&W Bridge" stamps is a "mock" bogus post and a fantasy, not a forgery and not a fake. I added to and mounted the collection formed by George Sloane (the person who corresponded with Gavit in above link) and that collection is online here (see frame 2 for "C&W" stamp):http://www.rfrajola.com/mocks/mocks.htm
add-on: I should also mention that Pomeroy's was NOT a local post although most catalogs lump together the 1844 Independent Mail Companies, including Pomeroys, together with a couple express companies and local posts under the convenient header of local posts.
Independent mails is a great field to collect and study. There is now an abundance of good resource material available (some less reliable than others). Try buying some real Pomeroys stamps or covers from a knowledgeable auction house or vendor.
