I was a nutty ebay seller for 5 years in a row where I never had fewer than 25+ listings going at any one time before they sucked the life out of the company.
mostly 37-54 Chevrolet parts, but I bought at auto swap meets as well as yard and estate sales and bought anything I thought I could make a buck on. nothing but old junk. I never listed anything without researching it beforehand to see what it was. you are already on the computer, go to the google and see what the heck it is. unless you are stupid it is not that difficult.
