Question About Dateds

My first posting! Glad to have found this forum. I have a question regarding Dateds. Is there a full listing of dateds that is available? How many are there? The most common ones I have are obviously MW, SRC and CMO (Chicago Mail Order). As for the lesser known ones, I have the following that need to be identified: QWHS, EWS, BNC, E.N.B., SB, NEP, P.CO, BEL, AI, BL/SP, GBC, APV, WNU & CTO. Are some dateds worth more than others? Thank you!

Welcome! I am sure some are more scarce than others. I am only familiar with SRC & MW precancels myself. I am sure someone will be able to answer your questions much better than I. If you are able to post pictures that would be helpfull in ID'ing the types on your stamps.

I was going to post picture, but decided not to for now. Most if not all are Bureau 61 & 71.

Here's the link you probably want:

If you're not prepared to buy the catalogs that give pricing and detail on all of the dated precancels, I find the "free" album page download to be helpful, as it at least gives you a start as to the various types of dateds that are out there.
