Pepre,
As I said in my earlier post, I don't collect Canadian postmarks and I do not know how many postmark collectors do so I can't gauge the market for your postmarks.
In the US states I collect, a package of postmarks of the same era (with no high cat value stamps) as cut corners like yours would typically go for $0.10 to $0.20 apiece. DPO's, RPO's, some slogan cancels and Last Day of Use cancels would command a premium.
Maybe this will give you an idea of how much effort you want to put into selling them. It's a niche market and sometimes buyers are difficult to find.
If you get over 50 posts and have decided to soak them, PM me before you do. I will contact the PMCC museum to see if they are interested. If they are interested, maybe we can make a deal. I will donate them to the museum. I hate to see postmarks destroyed!
Collecting postmarks can be interesting and fun. It's also a good use for all those covers with common definitives that you don't know what else to do with!
Dan
