Hello! That's a great question about the 1776-1976 Bicentennial half-dollar. The value of this Kennedy half-dollar really depends on which specific version you have, as there are two main types.
The most common version is the one intended for circulation, which is made of a copper-nickel clad composition. If you have one of these and it's been used, it is generally worth its face value of 50 cents. If it's in pristine, uncirculated condition, it might be worth a bit more to a collector, perhaps a few dollars. These coins were minted in Philadelphia (which have no mint mark) and Denver (which have a "D" mint mark).
The more valuable version is the one made for collector sets, which is composed of 40% silver. You can identify this coin by looking for an "S" mint mark, indicating it was produced at the San Francisco Mint. Because of its silver content, this version is always worth more than its face value. Its base value fluctuates with the price of silver but is typically several dollars. If the coin is in a very high, uncirculated grade, its value to collectors can increase even more, potentially into the $10 to $30 range or higher for top-quality, professionally graded examples.
So, the key is to check the coin's mint mark to see if you have the common clad version or the more valuable silver one
