The coin forum on ebay is excellent. They all gave me great advice and it paid off. I sold a decent size collection last year on ebay and did so much better than I expected. Word of advice tho', Ebay pretty much sets the standard on prices nowdays, and I learned after I sold some offline that I would have done better if I had not been so nervous about ebay fees. I did a fair amount of research and built a spreadsheet, then started on the low end, but came out closer to the high side. Hope this helps.
