Carach Angren wrote in How much is my Dragonbone worth?:Greetings all!
I was going through my D&D stuff and came across my old red dragonbone electronic number generator. These are great for a D.M., but as a player I preferred my dice. I originally paid $24.95 for it in the 80's minus my 20% discount for working at a hobby store. I have tried ebay, but none are listed. Are these junk that no one wants or hoarded in collectors vaults?

I would imagine that someone out there would like it.  It doesn't come up for sale often.  The value of your item depends on its condition, whether you still have the box or not, and possibly what color it is.  Therefore, it would be helpful if you posted a photo of it (and the box if you have it).

In looking over reviews and commentary, I saw where several people indicated that they wanted it, used it a few times, and then stowed it away, never to be used again.  Apparently, it sounds like a good idea until you actually have to use it.   

Cool dragonbone!  I can't imagine it would have been fun (or easy) rolling up a character with one.

I think that's the general area mine sold for as well. Maybe low $100s.

It's been a while since one has come up. If you know someone with a Worthpoint account, they can get some old auction prices for them. You can also join The Reseller Society Group on Facebook and very nicely ask one of the members there to look it up for you.

I'd say even without the box you could get $150 or more on eBay or the RPGAuctions Group on Facebook. Shoot, stick it up on eBay for a $250 BIN with the "make offer" option enabled - see if you get any bites. Couldn't hurt - Make sure when you list it, that you take a very great picture or two of the battery compartment showing that there isn't any corrosion on the terminals, and that there never has been. Do that with all battery operated electronics.

Good luck
