Not sure why you even ask the question. Lots of sites to check on what makes a note worth more than face value.
I think the question should be "Is it worth Selling?" If you keep it, it's not worth anything but if you keep it because you like it, then its "worth" something to you.. And if you spend it, it's worth $5
Trinary is an eBay term used when a note has nothing else going for it. If you like it, keep it. To me, it’s a spender.
