Sorry to burst your bubble Ellen, but the merchandise sold by vendors at the convention in Denver won't have much value, either. They are produced in huge quantities for sale to the public, and the thousands of leftovers are dumped on the hobby very cheaply. The Obama buttons that will be worth a lot of money are the short run buttons that come from the campaigns, and are specific in their content such as state, group or event. A Teamsters For Obama button picturing the President with James Hoffa is worth a lot of money. The mass produced junk from Tigereye is not. I have been tracking Obama buttons since 2002, and I have more than 3300 different buttons. I also publish my own newsletter, so if anyone wants any real information on Obama buttons contact me at davros@fgi.net.
