Because of the coin construction, it comes out to about 8.33% nickel, and the rest is Copper. The current quarter is made of a cupro-nickel alloy layered over a Copper core.
Beginning in 1837 and continuing through 1964, all half dollar coins were 90% Fine Silver and 10% Copper. The earliest half dollars from 1794 through 1836 were struck from roughly 89% Fine Silver and 11% Copper. Half dollars were made of similar materials to earlier dollar coins, with Silver being the primary metal and Copper gradually taking up more of the composition through the Kennedy half dollar, which was entirely cupro-nickel. Sacajawea, Native American and Presidential dollar coins are not commonly circulated but can occasionally be found in banks or in older vending machines and are more common in overseas U.S. They are currently minted and will continue to be minted into the future after the death of a President.Īll dollar coins stopped being minted for circulation in 2011 but are still available for collectors.

Newer dollar coins including the Sacajawea, Native American, Presidential and American Innovation dollars were created with a Copper core covered in manganese brass.
