rynegold Valued Member United States 249 Posts	Posted 04/24/2015 9:28 pm I have this coin: I looks cameo prooflike actually, however the planchet is damaged. It looks like a bubble that was rolled into the sheet from which it was stamped, burst during annealing and went unnoticed. My question is, has anyone else seen such as this before? I'm in the jewelry mfg. business now for my 38th year and have rolled/annealed my share of silver sheet. This is a common problem no matter who's doing the rolling... anyone else seen this before? Any added value for the mint's oversight? Comments anyone? regards, mitch Edited by rynegold 04/24/2015 9:34 pm Report this Post to the Staff

thedollarman Pillar of the Community Canada 4911 Posts	Posted 04/24/2015 10:55 pm I don't want to question your knowledge especially since you work with this stuff a lot and it is your living but to my eyes all I see is a hit that displaced some metal. And even if it is a planchette flaw is t looks distracting in a bad way and would be considered a mark against the coins eye appeal. Feel free to call me Will. Report this Post to the Staff

Half the pics say one thing, half another. OK (I'm editing this post as I go), it's confirmed incuse by another. Here's the trouble, rynegold, and I'm not stating it as if I have an answer because I don't. That bubble wouldn't have survived 150 tons of strike pressure, incuse or extruded. Look closer - with a strike that good, you should see metal flow lines. Perhaps/probably on the bubble itself. All the same, I can think of very little postmint which could come close to this without at least help from an existing planchet void, you know? I'm going to sleep on this one and revisit tomorrow.

Cascade Pillar of the Community United States 7390 Posts	Posted 04/25/2015 09:48 am Good call on the strike pressure SD. Can't wait to read your vedict on this one. @Rynegold, any chance of more pics at various angles with less light bleaching to show contours? How far out would you say the bubble protrudes? 1mm?

Halo1st Pillar of the Community United States 2775 Posts	Posted 04/25/2015 1:10 pm Possibly be a "ruptured gas bubble"? Rynegold - I think your analogy is close meaning trapped gas when the sheet was rolled to thickness, but the bubble formed from the pressure and heat generated as the coin was struck or by being heated after strike which the later is PMD. If the bubbles roof stayed in tact it would be an "occluded gas bubble". I read gas bubbles are a rare occurrence due to strike, but does happen. Most times looking like a die dent or gouge. Some may think its a distraction on a nice coin, while others will think awesome gas bubble. I'm trying to hone my gut feelings, but my gut reacts to what my eyes think they're seeing in a picture(s) so I could be right or I could be wrong as it appears to burst outward to me. At the same time I see the dark areas on the obverse, so I have to ask is that natural toning or was the coin heated after it was struck? Wait for an expert opinion as I'm still a learning rookie. Thanks, Doug. Report this Post to the Staff
SsuperDdave Moderator United States 23522 Posts	Posted 04/25/2015 2:56 pm As of right now, all I have is something postmint created the gouge - manipulating the images from the original stream shows one side a bit higher than the other - and the hole is to deep (and there seems too little displaced metal) to easily be all postmint. This may end up being a Holmes coin - whatever's left, however ridiculous, has to be it. Report this Post to the Staff
