PENNY
the 1861 Confederate penny was made of copper or nickel
A 1943 penny could be a "steel penny" as they were made of steel due to copper being needed for other wartime purposes. Nickels were made of 35% silver during WWII. If a 1943 penny and nickel were mixed, it would potentially be an error as they wouldn't have been in circulation together due to their different compositions.
Pennies in 1941 were mostly copper, not nickel, and they're worth about 5 cents.
A penny contains 97.5% zinc. A nickel contains no zinc at all.
Copper
The 1863 Indian Head cent is still the copper-nickel composition (.880 copper & .120 nickel) 1864 is the year they were first struck in bronze.
