No US coin, including the half dollar has a crown stamp on it when it comes from the mint. Instead, if you have a US half dollar with a crown stamp in it, it was done either by a private company or individual. These stamps generally add no value to your coin and it is just worth what a damaged example of whatever year of half dollar you have is worth.
The US mint did not use mint marks on the 1965 half dollar coin.
It's called a mintmark not a stamp and the coin is face value, the use of the "P" mintmark did not start until 1980 on the half dollars.
It is not worth anything
A crown on an old piece of jewelry was a way to signify that the metal is real. You would see the metal stamp and then the stamp of a small crown.
In the early 19th century, a British five-shilling piece, or crown, was sometimes called a dollar, probably because its appearance was similar to the Spanish dollar. This expression appeared again in the 1940s, when US troops came to the UK during World War II. At the time a US dollar was worth about 5s., so some of the US soldiers started calling it a dollar. Consequently, they called the half crown "half a dollar". The expression caught on among some locals and could be heard into the 1960s.

The half-crown and crown are obsolete British coins. Under the old pre-decimal system, one crown was worth five shillings, and the half-crown was worth half that. At twenty shillings to the pound, the crown was 1/4 and the half was 1/8 of a pound. Or, the crown was 60 pence and the half was 30 pence.
The blue crown stamp generally indicates that a stoneware pottery piece was made by one of over 200 Dresden potters registered to use the stamp. It is often counterfeited, so there is no guarantee your churn is from Dresden simply from the stamp.
Half a dollar is fifty cents.
Five. A sixpence (when they were in use, up to about 1970) was worth half a shilling. A crown = five shilling, so a half-crown = 2 and a half shillings.
