<p>[QUOTE=&quot;calcol, post: 2723154, member: 77639&quot;]I noticed an 1870 J-809 pattern half dime from the Newman collection currently being auctioned by Heritage (Apr 2017, lot 5103, see link below).&nbsp; There appears to be an active area of corrosion or toning at the base of the seven in the date.&nbsp; Same coin was auctioned in same holder in Dec 2013 (lot 3942) and in Mar 2014 (lot 10506), and there is no trace of corrosion at the base of the seven at either time.&nbsp; Seems rather strange for this to be happening in three years inside a slab.&nbsp; It may be something in or on the plastic because the location relative to the seven is slightly different in the whole slab view versus the close up.</p><p><br /></p><p>Cal</p><p><br /></p><p>2013 link:&nbsp; <a href="https://coins.ha.com/itm/patterns/1870-h10c-standard-silver-half-dime-judd-809-pollock-897-low-r7-pr67-ngc-cac/a/1192-3942.s?hdnJumpToLot=1x=0&amp;y=0#" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://coins.ha.com/itm/patterns/1870-h10c-standard-silver-half-dime-judd-809-pollock-897-low-r7-pr67-ngc-cac/a/1192-3942.s?hdnJumpToLot=1x=0&amp;y=0#" rel="nofollow">https://coins.ha.com/itm/patterns/1870-h10c-standard-silver-half-dime-judd-809-pollock-897-low-r7-pr67-ngc-cac/a/1192-3942.s?hdnJumpToLot=1x=0&amp;y=0#</a></p><p><br /></p><p>2014 link: <a href="https://coins.ha.com/itm/patterns/1870-h10c-standard-silver-half-dime-judd-809-pollock-897-low-r7-pr67-ngc-cac/a/1198-10506.s?ic4=ListView-Thumbnail-071515" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://coins.ha.com/itm/patterns/1870-h10c-standard-silver-half-dime-judd-809-pollock-897-low-r7-pr67-ngc-cac/a/1198-10506.s?ic4=ListView-Thumbnail-071515" rel="nofollow">https://coins.ha.com/itm/patterns/1870-h10c-standard-silver-half-dime-judd-809-pollock-897-low-r7-pr67-ngc-cac/a/1198-10506.s?ic4=ListView-Thumbnail-071515</a></p><p><br /></p><p>2017 link: <a href="https://coins.ha.com/itm/patterns/1870-h10c-standard-silver-half-dime-judd-809-pollock-897-low-r7-pr67-ngc-cac/a/1254-5103.s?ic2=mytracked-lotspage-lotlinks-12202013&amp;tab=MyTrackedLots-101116#" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://coins.ha.com/itm/patterns/1870-h10c-standard-silver-half-dime-judd-809-pollock-897-low-r7-pr67-ngc-cac/a/1254-5103.s?ic2=mytracked-lotspage-lotlinks-12202013&amp;tab=MyTrackedLots-101116#" rel="nofollow">https://coins.ha.com/itm/patterns/1870-h10c-standard-silver-half-dime-judd-809-pollock-897-low-r7-pr67-ngc-cac/a/1254-5103.s?ic2=mytracked-lotspage-lotlinks-12202013&amp;tab=MyTrackedLots-101116#</a>[/QUOTE]</p><p><br /></p>
