There are so many online groups devoted to collecting anything and everything imaginable on Ebay. Ebay is referred to as a guideline for going prices, availability(or rarity), and finding new variations of items unknown to a particular collecting community. I personally found a nostalgia for old video games, and discovered that a gaming community called ATARIAGE.COM had alot of resources to study a particular Ebay purchase I had considered. When I realized that I couldn't afford the purchase, I made it aware through a forum post under a marketplace heading, that these 2 semi-rare cartridges were on ebay. The selling price more than doubled soon after, and looking now I see that 15 people had viewed my posting on ATARIAGE. Using my passion of video games as an example, I think that if you research enough, you can find an online group devoted to whatever you have to offer. I'd like to suggest here that if you join a group in hopes of getting that better price for your item(s), that you do it respectfully, and make sure to find the appropriate place in the forum for it. I am getting ready to sell my old broken down car, a 1976 Datsun 280Z on here, and already belong to HybridZ, a group devoted to modifying and souping up those old cars. I'll definitely post to them for interest, and get more looks because of it. Have a great day! I hope y'all found this tip helpful, now lets get back to my favorite thing, Ebay-ing!!
