Because of the relatively large mintage of the 1970 Captain Cook 50c, because the public hoarded the coins in great numbers and because half a million of the coins were issued in specimen standard it's not that hard to find these coins in uncirculated condition. They are, therefore, not particularly valuable.
Kennedy half-dollar coins are not very rare and most of them are worth only their face value of 50 cents. However, some are more valuable, depending on the year they were minted and their condition. For example, a Kennedy half-dollar coin minted in 1970 and in uncirculated condition is worth about $8. F.V.
Like many of the early commemorative 50c coins the Silver Jubilee coins were hoarded away in great numbers, and you can easily buy a nice uncirculated coin for just $4 or $5. A coin from a mint set may fetch a couple of dollars more.
These coins were struck in abundance, with a mintage of over 25 million pieces. However, a few examples of 1977 50 Cents coinage later surfaced bearing the non-commemorative Australia coat of arms design used for previous and subsequent years.
1971 Kennedy Half Dollar Value
According to the NGC Price Guide, as of July 2023, a Kennedy Half Dollar from 1971 in circulated condition is worth between $0.60 and $0.75. However, on the open market 1971 Half Dollars in pristine, uncirculated condition sell for as much as $2050.
1976 50 cent with a mostly split planchet but the two halves have not detached. Planchet split around three quarters of the coin's rim forming the characteristic 'clamshell' shape that gives this type of error it's name. Not seen often on 50 cent coins.
Most of the 1974 Half Dollar coins are only worth 0. 50c, while the ones in mint condition sell for $2.50.
In Average Circulated (AC) condition it's worth around 50 cents, one in certified mint state (MS+) condition could bring as much as $3 at auction.
The United States Mint minted the 1971 Half Dollar. The coin features John F. Kennedy on the obverse side and the Presidential Coat of Arms on the reverse side. The coin is made of a copper-nickel alloy and not silver. A 1971 half dollar value is typically worth around 50 cents.
A really interesting error on a 1977 50 cent. It looks like it was struck through an attached cold shut. The smooth surface of the struck through area indicates a cold shut while the fractured edge shows that the cold shut was probably attached. Something quite different to a typical planchet flaw.
1976 was the first year, since 1971, that the US Mint was authorized to use 40% silver in their coin again. The 1976-S Silver Kennedy Half Dollar is in brilliant uncirculated condition and contains 40% silver.
Copper-Nickel Clad Coinage (1971-Date)
Mint mark: “S” (Denver Mint) and centered above the date. It is normal for 1971 through 1979 to be without a mint mark.
In 1943, the Lincoln Cent was supposed to be struck using a steel planchet covered with zinc due to a copper shortage because of the war. However, some leftover copper planchets from 1942 somehow ended up in the coining presses. This is arguably one of the rarest error coins in U.S. coin history.
1971 Denver Mint Kennedy half struck in 40 percent silver.
One of the key factors that drives coin value is rarity. Over 4 million proof silver dollars were produced in 1971 at San Francisco. So while the numbers are much lower than the mintage of regular dollars – especially those from other mint facilities – they aren't rare.
The 1969 D half dollar is worth around $6 in uncirculated condition with a grade of MS 63. Uncirculated coins with a grade of MS 65 can sell for around $30. The 1969 S proof half dollar is worth around $8 in PR 65 condition.
"The 1930 penny is considered a numismatic superstar, with its value only rising and its significance deeply established in Australian history, a once by-product of economic depression is now a symbol of prosperity, the ultimate cherry on top for any coin collector," Mr Hames said.
Both coins weigh 28.28 grams, and have a diameter of 38.61mm. The silver Proof coin would have been in a presentation box, but fortunately there is still a way to tell them apart with just the coins. The standard cupro-nickel coin would be 3.2mm thick, while the silver Proof coin would be 2.89mm thick.
