Aluminum bronze
Bronze (not to be confused with brass, although usage of the two terms varied in times of yore) is an extremely ancient alloy of copper and tin with origins going back to the period around 2,000 BC. Also known...wait for it...as the Bronze Age (who would have guessed?)
In contrast, the addition of the third wheel, aluminum, is a far more recent development, as the technique for extracting aluminum from bauxite was only perfected in the 19th century.
The proportion of aluminum used for this extremely corrosion-resistant alloy is generally 15%. Small quantities of other materials such as magnesium are also sometimes added.
Its is frequently used for coinage.

This initially obscure acronym comprising two words describing the state of conservation is explained clearly here:
Extremely Fine
This means – more prosaically – that the coin has circulated well from hand to hand and pocket to pocket but the impact on its wear remains limited: the coins retains much of its mint luster, sharp detailing and little sign of being circulated. Closer examination with the naked eye reveals minor scratches or nicks.
