What are these worth
 

I have a pair of Hertz Energy ev130's with crossovers and tweeters on basic custom wood-plates for an integra. The tweets are sent in for warranty at the moment but I'm contemplating putting these up for sale once the tweets arrive and I'm unsure of what they're worth. They are 51/4" and I replaced them with a component set of type r's I know they're quite expensive new, but whats a good used price to ask?? If they're not worth much I'll hold onto them as spares.
