Rockwell b hardness of copper
WebA comparison of the hardness of Lincoln Cents minted before 1982 and after 1982 yields some interesting results. The copper alloy used in pre-1982 cents is 45 on the Rockwell B Scale. (Olin, 9/3/2015) This converts to 76 on the 15T scale. (England, 9/1/2015) Conversion tables are known to be reasonably accurate, but not 100%.
