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.
The rarest mintmark for half dollars would be Carson City (CC mintmark) only a bit more than 5 million half dollars were minted at Carson City. While many times that were struck in San Fransisco, Philadelphia, Denver and New Orleans.
Depends on the mint, but if it is P(no mint mark) then a circulated piece will be about $10. The rarest is probably Flowing Hair Halfs only made in 1794 and 1795
Overall, the rarest year would have to be 1921.

You can,t a million dollars interest from a million dollars but you can get half a million dollars
....They haven't stopped being made. New Kennedy half dollars are minted every year. 2001 is the latest year intended for circulation, but you can buy 2011 Kennedy half dollars in mint sets and in bags on the mint's website.
I assume you mean Franklin half dollars issued by the U.S. Mint. If so, see the attached link. If you're referring to coin-like pieces struck by the Franklin Mint, could you please post a new question with that detail?
The rarest would be the 1978 God Loveth a Cheerful Giver, its estimated value is around 536 US dollars.
No 1963 Kennedy half dollars exist. 1963 is the last year of the Franklin half dollar. 1964 is the first year for Kennedy.
1964 for dimes, quarters, and 90% silver half dollars, and 1970 for 40% silver half dollars.
The US Mint did not produce any half dollars in 1922.
Half dollars from that year contain 40% silver and are worth around $5.
