History: America issued its first Revenue Stamps in 1862 to help fund the Civil War. The first issue included 25 different types of stamps for various uses. Among these were stamps for use on proprietary articles. These proprietary items were consumer goods, including medicines, matches, perfumes, playing cards, canned foods, and more. Between 1862 and 1871, there were eight proprietary stamps created as part of this initial Revenue issue. (from Mystic Stamp Discovery Center)
