<p>[QUOTE=&quot;Troodon, post: 140753, member: 4626&quot;]65-70 half dollars actually are clad... they were made from a core that is 20% silver, 80% copper, with clad layers that are 80% silver, 20% copper.&nbsp; Overall they are 40 % silver by weight, but unlike the 90% silver halves from 1964 and earlier they are not a solid alloy.</p><p><br /></p><p>From 1971 to the present they have a core of pure copper with clad layers that are 75% copper, 25% nickel.&nbsp; Exceptions are 40% silver proofs and business strikes bicentennials minted 1975-1976 by San Francisco (they also minted clad proofs) and 90% silver proofs in silver proof sets and heritage proof sets.</p><p><br /></p><p>As to how to tell, from 1964 to 1970 it&#039;s easy to tell just by the dates.&nbsp; All proofs of these were minted in San Francisco... to tell the difference between a clad proof and silver proof is easy just to look the edge; the clad proof will have a copper stripe in the middle while the silver will have a solid silver edge.&nbsp; 1965-1967 don&#039;t have true proofs... there were special mint sets put out, some of them near prooflike.[/QUOTE]</p><p><br /></p>
