The value of a 1961 US half dollar depends on its condition and mintmark. The regular-issue 1961 half dollar, minted in Philadelphia and Denver, has a melt value of $5.65 based on the current spot price of silver. However, because of its age and relatively low mintage of 101,000, it typically sells for a bit over its melt value, anywhere from $7 to $10 or more depending on its condition and whether or not it is certified.
On the other hand, the 1961 Proof half dollar, minted in San Francisco, carries a significantly higher value. With a mintage of only 2,002 pieces, it is quite scarce and is actively sought by collectors. The value of a 1961 Proof half dollar can range from $100 to $200 or more, again depending on its condition and certification status.
