<p>[QUOTE=&quot;JeromeLS, post: 1533647, member: 7867&quot;]The chemical compound polyvinylchloride, a common constituent of old plastic coin flips (and some cheap modern ones), will react with silver and base metal, corroding the surface of the coin. To my (fairly untrained) eyes, it looks like that&#039;s what caused the yellow residue on both sides of the coin, and some of the damage has been &quot;corrected&quot; on the obverse. Worth about $200 if not less. It&#039;s a scarce issue.[/QUOTE]</p><p><br /></p>
