The 1976 Bicentennial 24K Gold Plated Kennedy Half Dollar, Brilliant Uncirculated, is a novelty item rather than an official U.S. Mint product.
These coins are typically made by private mints or companies that gold plate regular Kennedy half dollars.
Because they are not official mint issues and have been altered by plating them with gold, they generally do not hold significant numismatic value beyond their face value.
The value of these gold-plated coins is mainly sentimental or decorative, rather than being based on precious metal content or collector demand.
However, if you enjoy these coins for their aesthetic appeal or as part of a collection, they can still have value to you personally.
As always, it's advisable to be cautious when purchasing such items and to buy from reputable sources if you decide to acquire them.
