Yes people can still bid..however...you will get more bids if you verify your account. I let's bidders know that your being serious about your listings. Is this a pack pulled autograph or did you or someone else get it signed elsewhere? Do not take this wrong...but a lot of new members tend to not mail out auctions they post...that's the reason you have no bids...you'll need to build up your feedback a bit...then you'll get the bids coming in...but hey..everyone's gotta start somewhere right....very nice card...best of luck to you!!
One thing that might help is if you included more info on the card. The year and product would be a start then also include if this was a pack pulled auto or an in person auto.
