Thoma Wilson Julep Cups

Q I have three Derby mint julep cups signed by Thomas Wilson and dated 1985. I know that they sell for $250 new. What can I ask for these cups? They are in mint condition.

A Thomas Wilson was a metalsmith and jeweler who made bookmarks, keychains, letter openers, and jewelry. According to Wilson Artworks, the first julep cup was made for a friend to be given at the Hardscuffle Steeplechase in 1978. After that, cups were made for corporate customers, colleges, schools, sporting associations, weddings, and QVC-TV. The cups are made of copper and plated with silver. Wilson developed a method of using machines for part of the process. After Wilson died in 2009, his wife has carried on the business. The company is still in business making julep, tippler, and jigger cups in both silver and copper. Value of your cups, less that $50 each.
