A Lot of Copper Is Used in Building Construction
#2
Of course most of us can remember how, in 1943, our pennies were made of stainless steel (actually zinc-plated stainless steel) because demand for copper soared whenever a major war is on.

Nickel is also a critical war material - leading to nickels having been made of 56% copper, 35% silver, and 9% manganese from 1942 through 1945 instead of the customary 75% and 25% nickel.
"These, and many other matters which might be noticed, add a volume of unofficial declarations to the mass of organic utterances that this is a Christian nation" - Justice David Brewer, Church of the Holy Trinity v. United States, 1892
