<p>[QUOTE=&quot;desertgem, post: 2097890, member: 15199&quot;]For the clad dime, the nominal weight is 2.268 grams and the tolerance is +/- 0.09 grams.</p><p><br /></p><p>Acids acting on coins&nbsp; leave a smaller version of the original design as it attacks evenly on a clean surface, so the raised head of the obverse will reduce as much as the flat field, so the design stays proportional, just decreased dimension. However acids have different reaction rates on different alloys, so the cladding ( 75% copper and 25% nickel) will react slower and less than on the 100% copper core. However on both ( cladding and core) the original structures such as obverse and reverse design and the&nbsp; reeding with be decrease proportionally ( peaks and depressions) so a reeding will still be visible.[/QUOTE]</p><p><br /></p>
