,....mhhh although I am"Swisstralian" and collect my old country among a lot of other countries and themes, this "Number" issues are not that easy to "identify".
It is a little ,like KGV or the "uglies"
I will show you a few pictures and lists, which I scanned from the Zumstein catalog 2007 with the hope, not doing anything illegal regarding Â©

1881 Zumstein # 52 printed on "paper with blue and red short threads"

Regarding the cancellation of above stamp, it looks a little ? to me, so it needs to be certified.
I need you to know, that any and the slightest imperfection in perforation and sharpness of the postmark is "greatly down marked".
The prices in Zumstein are for fault free, average copies.
Excellent condition will ad 100 - 200% value.
Poor condition = space fillers!!!
