I guess there's still some controversy on whether or not these are legit. But for a $45 box of glass plates (who does those anymore?) of really nice photos they're worth something a little more than that regardless.
Rick Norsigian made one of the best yard sale deals ever.
Ten years ago, the California painter bought two boxes of photographic plates for $45, after he bargained the owner down from $75. Today, they are worth an estimated $200 million.
