only 1 or 2 known
If you mean a Franklin Half dollar the 1955 Philadelphia issue is the lowest mintage.
There were only 3,918 Half Dollars minted in the year 1796 making them, probably, the rarest and most valuable. Average circulated is worth $8,000.00, extra fine is worth $46,000.00. There are no known uncirculated ones.
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.
1921
The most valuable wine from year to year is probably Ch. Petrus from Bordeaux. It initially goes on sale for $1200 a bottle.
The last year British sixpences, shillings, florins, and half crowns were made with silver was 1946.
1895
The New Zealand Halfcrown was issued in most years from 1933 to 1965. Any collector value would depend on the year and condition of the coin.
The half crown coin was minted in the United Kingdom until 1967, with the last coins being produced that year. Therefore, there were no half crowns minted in 1968 or 1969. The coin was officially withdrawn from circulation in 1970 as part of the decimalization process.
Depends on the year, company and condition.
