Nickels never change? 1866-2022
The composition of nickel five cent pieces in 2022 is identical to the original 1866 piece. 5 grams of 25% nickel, 75% copper.
War nickels excepted, they have never changed composition. I've heard the mint has considered changing the metallic content many times but never has. Why is that?
Amazing after 156 years they remain the same. The last "real" circulating money perhaps?
