I love this statement from the article:
They finally decided to use an alloy of copper, silver and manganese. It may not seem practical today, but in 1942 the silver in the revised nickel was only worth one or two cents.
This statement really caught my attention too:
By the 1960s, wartime five-cent pieces were worth more than face value. Millions were melted, despite the Mint director’s warning the meltings were not in the public interest. In 1966, silver-alloy nickels were worth seven cents. Massive meltings resulted in a severe shortage of five-cent pieces in New England.
