Frequently Asked Questions

Are 1976 Bicentennial half dollars worth anything?

Most 1976 Bicentennial halves are worth face value (50 cents). The 40% silver versions (sold in mint sets) are worth $5-$8. Error varieties can be worth $20 to $500+.

How do I tell if my 1976 half dollar is silver?

Check the edge. Clad coins show a copper stripe. Silver versions have a uniform silver-gray edge. Weighing is the most reliable method: silver = 11.50g, clad = 11.34g.
