I came across my first perfin stamp recently (yes I'm new to it all) and I mounted it today in my "world" album. Having looked up the code online it seems to relate to the Canadian National Railway or CNR per the perforations. Pics below.
What are other peoples thoughts on perfin stamps? Do you mount them in your main albums or do you separate them and put them in a perfin only album? Maybe you ignore them entirely?
For years many collectors regarded Perfins as damaged stamps not worth of album space (and some still do!)
They have however always had a hard core of followers and researchers and as lists identifying them have become more accessible the number of collectors who no longer reject them is increasing.
Personally I would still not mix them in an album page of regular used stamps for appearance , aesthetic reasons , some are less attractive than a clean used stamp with a neat cancel.
So I would have at least a separate page or two for perfins alone and do the same for precancels. I feel the best way to do justice to them is to display separately, usually face down to show the white reverse side in black mounts.
what ever it is , it's better than a poke in the eye from a wet umbrella!
I mix mine up with the regular album pages. Since I usually find them after the pages have been printed, they are mounted backwards somewhere on the page. I don't actively collect them, but when I do come across them, I keep them! There are all kinds of perfin's, just too many to collect. I'll settle with the odd one here or there.
I do put aside all perfin I do find. But I do not orgnize them in anny way. I they are used in my ordinary collection it must be because it is a hard to find stamp. But I think I saw a CNR perfin this weekend in my stock book.
