Pretty rare, usually. This is what's referred to as a "Tag" or "Laundry Tag" patch. Your particular card is SN5, and that's actually one of the higher Panini Tag patches I've seen; usually they seem to be SN1 or SN2.
I'll never quit collecting entirely, but I am downsizing. Check out my COMC store and help me thin out what I don't want so I can buy cards that I do want. See something you like? Send me a message on here, and we can knock the price down quite a bit. I'll even take a bit of a loss if it means getting you a card you really want.
