I have been buying and selling on ebay since it opened up... heres a few things I learned...anything harley sells... I pick up anything at yard sales that I think will sell, all collectibles, like name brand or high end china n dishes and figurines. High end genuine purses like dooney and bourke and coach..but make sure you know the difference between real and fake as theres alot of fakes out there.. I also pick up old clocks, electric and battery operated, working and non working, older bar stuff, like signs, mugs, steins.. I just list all my items with lots of pictures and am totally honest on my description, if its cracked or scratched or broken, I tell em in the description.. honesty is the best policy...
My best find and sale on ebay was a small cabinet vase I paid 25 cents for.. it sold on ebay for 450.00 and was sent to Japan. it was only like 4 inches tall..had the french crosses embossed all over it...made in the late 1700's by daum Nancy in france... I litereally fell right off my chair on that one... and I was gonna throw it out...lol...
all jewelry is a good seller too especially those that are marked by the maker..
