Earlier today, the U.S. Marshall's Service previewed nearly 500 possessions of Ponzi schemer Bernie Madoff and his wife, Ruth, that it will auction off on Saturday. Up for grabs: a bed, piano, 10-carat diamond ring, and shoes. Lots of shoes.

The sale is expected to do better than last year's auction, which raised $1 million. A few photos of the items below. [Click photos to view full-size]
