What I did was list everything on CL. I made lots of some things (ex. a box of cloth, 10 shirts etc.) and listed big ticket items separately. You will be surprised how far people will drive for a 5 or 10 dollar item. It took a little longer but I didn't have anything stolen (including money). I never listed my phone number, I could weed out people from their emails and only dealt with people I wanted too. Of course, I never set appointments for when I was home alone and I also said to bring correct change because I did not keep any cash at home. If I were going to really be selling a lot of valuables I would use a company that handles estate sales. It will surprise you how many people come to yard sales to steal.
