<p>[QUOTE="Kentucky, post: 1493473, member: 33176"]Since it is a 1960, it should be a 95% copper coin and weigh 3.11 g. If it is lighter, it could be an off-metal error on some kind of blank. Most likely it is plated and should weigh the 3.11 g or more. A popular high school chem lab is to zinc plate cents and then change the thin zinc coating to brass by heating the coin. The safest thing is always - Take it to a dealer. You may not agree with what they say, but they can see the coin "in-hand".[/QUOTE]</p><p><br /></p>
