<p>[QUOTE="usmc60, post: 2526750, member: 76739"]Let me just say very good presentation. Kudos JMHO HO.now I think you're talking about the ops coin. I agree it's a nice piece and I too would not mind having it in my collection. And you have no argument by me on your statement. What I've been able to find out as the sheet come out of the press and is set to the roller it is also scanned for defects. And a majority of the defects are detected by scan. And is handled properly at the foundry. But in the case of Dave's coin that is an internal defect. And not detectable. Only after being hit by the die causing that area of contamination to crack along the weak points. And after a closer visual examination somewhere not too far in the past that missing piece of brass was actually pulled off. The espressos brass is a good indicator of that in the damage area. And 90% of the surrounding coin is still 95% brass and 5% zinc.Solid I presume with no missing pieces. It's hard to tell without a full photo.All I'm saying using the word lamination in describing older coins I personally have a problem with. Newer coins no big problem.<img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie6" alt=":cool:" unselectable="on" unselectable="on" /><img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie24" alt=":blackalien:" unselectable="on" unselectable="on" />[/QUOTE]</p><p><br /></p>
