Set for release May 20 2011, the "Rub and Sniff" design is one of the few scented coins in numismatics.

Distinctively leaf shaped, this iconic 2011 coin releases the aroma of cannabis when the reverse is rubbed. An official Benin legal tender issue, the obverse is distinguished by the national Coat of Arms.

The Republic of Benin is a country in West Africa. It borders Togo to the west, Nigeria to the east and Burkina Faso and Niger to the north. Its small southern coastline on the Bight of Benin is where a majority of the population is located.

The capital of Benin is Porto-Novo, but the seat of government is located in the country's largest city of Cotonou. Benin covers an area of approximately 110,000 square kilometers (42,000 sq mi), with a population of approximately 9.05 million.

The Benin 2011 Marijuana Scented Silver Plated coin will be available for $79.50.
