Some people swear on Sedo and have great success, the GoDaddy auctions seem to take forever and most times you still end up with the domain, eBay use to be a great place to sell them but now a days they may be a option if they are non-adult, if they are good domains and ring someones bell they will probably sell pretty quick here on the Buy/Sell, unless you are looking for xxx,xxx$ for each then it may take a while
Good luck with them and I am looking forward to see what you have for sale
