On eBay? No idea. If you put the words "rare" and "antique" in the description you can always charge five times what something is worth. Not that anyone will pay it, but you can charge it.
Here, it comes down to color desirability and condition. Beaters go for seventy bucks or less. Rare colors in mint condition - about double that or maybe more.
I agree with Steve about
batteries. Not a consideration for me either in figuring what I'm going to pay for something. Don't care what people had to say about the condition of the batteries, more often than not they were bad or on their way out when I got them. At least for some of us including them won't mean you get more for the PV itself.
Ultimately all that matters is if you price it too high you will know because it won't budge.
