<p>[QUOTE=&quot;Spark1951, post: 8126458, member: 90692&quot;]I’m currently working on Roosevelt clad dimes.&nbsp; I noticed a prevalence of deterioration on even the best of them, none are uncirculated, all pocket change AU53-58+ over the last 60 years or so, having varying degrees of deterioration:</p><p>1.&nbsp; striations in the fields radiating toward the rims (not polish lines), both sides.</p><p>2.&nbsp; eroded letters and numbers, mostly adjacent to the rim, both sides.</p><p>3.&nbsp; An “orange peel” effect to surfaces, including the bust in some instances.</p><p><br /></p><p>My question is:&nbsp; Is there any degree of deterioration deemed acceptable?</p><p><br /></p><p>For an example, an AU58+&nbsp; has very slight wear, good luster and well struck devices, both sides.&nbsp; BUT…it has eroded letters and date with striations at the bottom of the letters and a halo of striations inside and outside of the numbers of the date.&nbsp; Sometimes the obverse has less deterioration than the reverse, US of A seems especially susceptible.</p><p><br /></p><p>With a 12x loupe you almost can’t see the deterioration, but magnified with a scope it shows right up.&nbsp; What I have resorted to is culling out the worst of them.&nbsp; From 1965 through 1990 I have removed 38 dimes out of 84 (so far).&nbsp; I kept wear and weak strike separate from my observations as much as possible.&nbsp; I can supply pictures, but they are on my Lab computer, I’ll have to switch to post them.[/QUOTE]</p><p><br /></p>
