<p>[QUOTE=&quot;Neal, post: 3607307, member: 43872&quot;]I suspect you could get that effect of the reverse mushy with a strong obverse by several means.&nbsp; If the obverse were coated with oil or wax before dropping it in acid, for example.&nbsp; Another method might be to place it in a shallow amount of acid that did not reach the obverse, but that would be harder to maintain the uniform etching of the edge.&nbsp; </p><p><br /></p><p>It would seem to me it would be much easier to explain that obverse/reverse difference by assuming acid than by supposing it was struck that way, whether it was a dime planchet or a foreign one.&nbsp; A coin struck on a too-small planchet would have roughly equal pressure on both sides.[/QUOTE]</p><p><br /></p>
