<p>[QUOTE="Conder101, post: 3024043, member: 66"]The coinage act of April 22, 1864's specified the composition of the bronze one cent piece to be 95% copper 5% tin and zinc. It did not specify any specific ratio of the two metals tin and zinc, so the mint was free to use any combination of the two that added up to 5% of the total alloy. This is why in 1942 with tin being in very short supply due to its use in the war effort the amount of tin in the 1942 cents was reduced to a mere trace. The entire mintage of 1942 S cents used only 50 pounds of tin. From 1946 to 1963 the percentage of tin in the cents varied.[/QUOTE]</p><p><br /></p>
