If I found it, I would keep it because the serial number is interesting and it's only a dollar. I would not pay over face but I'm sure some bid-idiot on eBay might give you something over face. It's condition kinda sucks and it's not a quad pair. A quad pair is AABBCCDD and there's no such thing as a "very cool trinary" . Trinary is a hype term used on eBay to separate unsuspecting newbies from their money.
