I'm visiting Cuba soon and have just read an excellent answer about the Cuban CUC and CUP bank notes.
I have a retired friend who collects bank notes and I usually bring him back some low-value bills from interesting places - but I see it's forbidden to "export" CUCs.
My question is, if I wanted to bring 1 or 2 of low-denomination CUC and/or CUP notes out with me, am I going to be searched & in big trouble if discovered or are they only worried about taking big bundles of cash out?
