In case your question is serious, it's a generic currency symbol.
Supposed to be used in the same way as $ and £. It's rarely used, but I have seen it on occation.
I was wondering, because I suddenly remembered the dollar sign in (hehe!) ABC80 Basic was replaced with this thing, and I couldn't understand why! Perhaps it was some bizarre dislike for America in general and its currency in particular that prompted SI (the swedish standardization institute, for you foreign peeps) to make the change.
I'm a collector of useless info, and if I die without seeing another ABC80 (or ABC80 emulator for that matter) I'll die a happier man. Damn, that f'n machine sucked bad!
