Abstract
The artifacts of hemp and marijuana's rich histories are some of the hottest articles on the secondary market today. Revenue stamps issued under the Marihuana Tax Act of 1937 were recently auctioned by the Smithsonian Institute to raise money for future acquisitions. The prices received shattered all preauction estimates. Other collectable stamps have been issued by various states of the United States (US). The high values of these items and other collectibles reflects the huge investment the US government has expended in trying to eradicate the use of Cannabis.Collectors should be aware that the high value of these stamps reflects on the current hot market for collectibles of all things Cannabis.
