Due to the federal raid on Liberty Services, the national office, the numismatic value of Liberty Dollars is skyrocketing. Ron Paul gold liberties are going for over $3,000. Several one ounce Ron Paul silver liberties are selling for over $400. Ron Paul Copper Liberties (face value of $1) are going for over $50!
While I think this will be a temporary situation, it is indicative of the fact that these things have value. Once the government loses their criminal case, the price will drop back to something closer to normal.

As John commented, "Do you know that people are coming all the way from Charlotte to visit my store!? That's over 50 miles away! All because I'm the only store in the area that gives out silver as change!"
