Is a 1776-1976 Half Dollar that appears to be solid silver worth anything It looks like a 1964 silver coin not like copper centered ones after 1965?

Answer 1

The first thing to check is whether there's a mint mark located above the date. If there's none or a D, you have a regular clad dollar that was silver-plated. A lot of private companies took regular clad Bicentennial coins and plated them with silver or more often gold, and sold them as "collectibles". Unfortunately the market tanked after the end of the Bicentennial celebrations so these aren't worth much except to a few niche collectors.

OTOH if your coin has an S mint mark it's possible that it's one of the 40% silver issues made for sale to collectors. Their value fluctuates with the price of silver but as of late 2009 they retail for $7 to $8.

If you can get a sensitive scale, it's possible to tell the difference between a clad and a 40% silver Ike. The former weigh 22.7 gm, while the latter are 24.6 gm.
