I plan to list some hippie-era clothing on eBay. Two of the items are vintage Granny Takes A Trip men's velvet trousers which are in pristine shape-quite nearly new. Most of what I encounter on ebay is more mundane. How can I tell what sort of value to use as a reserve on these? I'm only willing to sell if I can get a good amount for them; However, I feel that someone out there may be able to actually wear them and they are far too great to just spend their lives on a hanger in my closet!Thanks.
