Expert Profile: Mark Leon

Expertise: I am a collector of United States postage stamps, and also a stamp dealer. I`m a member of the American Philatelic Society (APS). My principle area of interest and expertise is in United States Stamps.
I've been selling stamps on the internet since early 1996. I maintain a stamp web page that concentrates on mint US stamps issued generally between 1890 and 2004. I'm an active seller on ebay.com since 1996, under the user id "mleon". I have a Bachelor of Science degree in computer science from the University of Nevada at Las Vegas, 1984.
