The 1964 Kennedy Half Dollar is a cool comparison. These are 90% silver, giving them a solid melt value (around $13.02 as of today).
That's a big difference from Wheat Pennies, which are primarily copper or steel. However, like Wheat Pennies, certain 1964 Kennedy Halves are incredibly rare.
The 1964 Special Mint Set (SMS) examples can fetch up to $156,000! This echoes the error coin wheat penny value, such as a 1943 Bronze which is worth a cool $1.7 Million!
The 1979 Susan B. Anthony (SBA) Dollar is made of a clad composition (outer layers of copper-nickel bonded to a core of pure copper).
These are generally only worth $1, but some error examples can be worth up to $15,000!
While impressive, it's still not in the same ballpark as that $1.7 million 1943 Bronze Wheat Penny. This error coin Lincoln wheat penny value continues to reach record highs.
Morgan Dollars are 90% silver, giving them a higher base value (around $27.85 in melt value as of today) than most Wheat Pennies.
However, like Wheat Pennies, the real money is in the rare dates and errors.
For example, the 1893-S Morgan Dollar can be worth over $2 MILLION! That said, while we're on the subject of rare pennies, remember the 1903 penny coin value for a moment.
Looking more broadly at half dollar coins, you see the same pattern: silver halves (like those from 1964) can range in value from their melt value (around $13) to incredibly high sums for rare errors, such as the $156,000 one previously mentioned.
This mirrors the world of Wheat Pennies, where a common coin is only worth a few cents, but a 1943 Bronze can be worth $1.7 MILLION.
