<p>[QUOTE="Clawcoins, post: 3142807, member: 77814"]I'd guess that 1999 die chip .. being Round .. is probably a plating blister/bubble or an alien. You'll see a lot of plating issues from 1982 forward as it's such a thin layer of 2.5% copper plating over a 97.5% zinc core. From 1982 and before it's mostly a 95% copper round.</p><p><br /></p><p>the other stuff is kewl and I'll leave it to the experts[/QUOTE]</p><p><br /></p>
