Pending on where you live there some other alternatives. Using Google or other search sites try to find a coin show in your area. Or even a coin club. If you find a coin show, you may want to try selling at one or going there and see what you would be offered for the entire collection. Same at a coin club. Although most coin stores would really try to low ball you on prices, if you find the right one, might get a decent price for the entire collection and no postage, nandling, insurances, paypal fees, lost in the mail, etc.
Or as noted stick around here until you get enought posts and then sell them here.
