<p>[QUOTE=&quot;RonSanderson, post: 24872546, member: 77413&quot;]I first posted this coin about 7 years ago, so I must have bought it just before Christmas 2016. Here&#039;s the image from then. I don&#039;t think it was really this yellowish - my photos have improved since then!</p><p><img src="https://www.cointalk.com/attachments/01c-1924-s-full-02-jpg.582403/" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p><br /></p><p>I have had occasion to take more recent photos, which revealed the coin in this condition. If you look at the expanded version, you can see what looks like varnish or some other crud. See the inside of the ear, the front edge of the forehead, and at the rim above and below LIBERTY.</p><p>[ATTACH=full]1596287[/ATTACH]</p><p><br /></p><p>I was thinking of looking for a replacement, but 1924-S coins are notoriously weakly struck and this is actually a pretty good example. I decided to see if I could undo whatever happened to it.</p><p><br /></p><p>First, I rinsed it in distilled water. I put the water into a small container, gently held the coin, and swished it around vigorously. Occasionally I changed my grip to make sure every part of the surface was equally rinsed.</p><p><br /></p><p>Then I rinsed it in acetone, using the same method, then finally xylene. This took about 10 minutes altogether. I took some more pictures and it looked like there was still some crud on the left wheat stalk. I took it back to the lab (my workbench in the basement) and gave it about 100 more swishes each in the water, acetone, and xylene.</p><p><br /></p><p>Enough talk, here&#039;s the results.</p><p>[ATTACH=full]1596298[/ATTACH]</p><p><br /></p><p>Full resolution photos</p><p>[ATTACH=full]1596296[/ATTACH]</p><p>[ATTACH=full]1596297[/ATTACH]</p><p><br /></p><p><br /></p><p>What do you think?
