I won several bids with Jennifer Black in the Seattle area,. Or so I thought. A Joe DiMaggio baseball with a COA. I sent it to JSA for authentication but they said there were to many irregularities to authenticate. So there went 600 dollars. Then I won a painting that I was charged 41 dollars to ship to me. When I got it the back had been taken off and the frame was falling apart. They almost always take the frames apart to make sure there is nothing of value hiding behind the painting. Unfortunately they don't fix it before shipping. I strongly recommend only using these auctions if you can personally go to pick up the merchandise. Also it is very common for these sites to have people raise the bids with no intention of actually buying. These sites as a whole are less than honest and my advise is stay local or stay away. I tried to get a response for my bad items but got nowhere. BUYERS BEWARE
