Silver half dollars have been a part of US currency since the late 1700s. The first silver half dollar was minted in 1794 and was made of 89.2% silver and 10.8% copper. The design of the coin changed over the years, but the composition remained the same until 1873. After that, the coins were made of 90% silver and 10% copper. The US Mint stopped producing silver half dollars in 1964. However, the coins are still highly sought after by collectors. The value of a silver half dollar depends on its condition, mint mark, and year of mintage. For example, a 1794 silver half dollar in good condition can be worth up to $10,000.
