I'm not sure what you mean by "one head". ALL Kennedy halves only have one image on the front side.
Anyway, if its date is 1964, it's worth about $6 for its metal content. 1965-69 have less silver and are worth about $2.40. 1971-now are made of copper-nickel and are only worth face value.
Nothing, because it's a fake.
$60.00 to $80.00 in circulated condition.
Circulated condition $20.00 to $40.00
It's a novelty item called a magician's coin, and it's not a silver dollar. Kennedy is on the HALF dollar, and silver dollars haven't been issued since 1935. All half and $1 coins made since 1971 don't contain any silver - they're either copper-nickel or brass. Its not worth anything Kennedy sucked
1914 would have made it a Liberty head (or Barber) style half dollar. Pictures can be found online.
Minimum of $24, one in perfect condition can be worth $8100 or more.
A 1902 Morgan still in collectible condition is worth about $33.00
Money can have various values based on condition and certain stamping. An 1885 Morgan Liberty Head silver dollar can be worth between $20 and $400.
WHAT IS THE VALUE OF LADY HEAD DIMES AND BUFFALO NICKELS WORTH TODAY? AND THE VALUE OF OF GOLD DOLLAR CIONS AND SILVER DOLLAR BILLS?
$15.00 to $20.00 in circulated condition.
Sorry the US never struck any half dollar gold coins of any date
It's 50 cents that's all
