selling the government

I know that presidents use many items one time and then move on. Many pens become collectibles simply because a president used them.

I am thinking, why not ebay these items from the government to the people of the world. Think of it. Every day the president uses a pen or two. Each day that pen comes up for auction with a certificate of authenticity.

The pen would be labeled nicely as a white house pen and then sold. Think of items like sheets used in the Lincoln Bedroom (of course they would be cleaned prior to selling). Or even items like executive desks that were used by the president or other high officials.

I know this means more pens would be used. However, the government could raise money without taxes.
