No, put them on a website that everyone will see. So it attracts people attention. Sure you can go door, but that wastes time and energy. LOL
You can sell anything if you are a good salesman. In my experience, anyone can sign a card, its only worth something if you have an official COA (certificate of authenticity) to go along with it.
In today s recession, I just do not believe that people are willing to spend money on collectibles, especially when they are losing their homes. I have a hard time selling on sites like eBay and Beckett and there I am targeting a group of individuals that want what I have to sell, You would be better off investing some money in third party authentication sites for autographs and if you truly have something of value, people will buy it recession or not. ie..Mark McGwire autograph (which are hard to come by) perhaps any players that are deceased as well. I hope this helps...
It probably would but I think online is easier.
