Where to ask "WIW" ??
This ain't a WIW forum. We don't do auctions here and that's the only way to find out WIW. If you want to do it here, decide on a price and post it in the for sale forum like everyone else. You have the same internet access as everybody else. You can look on Ebay and everywhere else and see what similar items sell for. There's nothing special here that will make your item any more valuable.
