Hi TripleAMom. The most important thing about selling on eBay is selling items that you like and enjoy. For instance,a decoy duck will make a heck of a lot of money, but if you don't like them or can't find them, it doesn't matter.
Auction off what you like, and items you are likely to find in local estate sales.
also be cautious about the size of the items - if they are large items, auctioning them off is hardly worth the hassle of wrapping and packaging. Ideally, auction items that will fit into reinforced envelopes.
