If this stamp turns out to be genuine, it could make a retired couple in Dresden millionaires. A 70-year-old man bought a 2 kilogram bag of old stamps at a local flea market for 20 euro. When he got home, he discovered that one of stamps in the bag looked like a rare "one cent" stamp from the USA. The 1861 stamp with the image of Benjamin Franklin is valued at 2.5 million euro ($3,206,000). There are only two authenticated stamps of this kind in the world. This could be a dream come true for the stamp collector and his wife.
