Aluminium 上市 Deposited
A grayish- white metal resembling silver in color but of much lighter specific gravity. It is used extensively for tokens and medals, but the employment of it for actual coins has proved rather unsatisfactory.
For British East Africa and Uganda aluminium Cents and half Cents have been issued, and a one-tenth Penny was struck for Nigeria in 1907 in the same metal. It has also been employed as a money of necessity by Germany in 1916-1917.
