R Michael New Member United States 20 Posts	Posted 03/15/2006 8:32 pm Hello all, newbie here, and after searching this forum I couldn't find anything close to what I have. I picked this quarter out of change recently,I still carry my habit learned in my youth of looking through my change. Any way I have never seen edging such as this. It is like the center sandwiched section has shrunk. As you can see in the photo the knurling is still present so it hasn't been ground away and it is an even depth all around the perimeter. Can anyone help? Thanks! Mike Image: 1-4edge.jpg 83.89 KB Report this Post to the Staff

toast Pillar of the Community Australia 1091 Posts	Posted 03/15/2006 9:32 pm I have seen coins from other countries that are minted that way on purpose as part of their currency(An example is a 1950 Mauritius one rupee coin) but that does not have a copper core. So you may have a USA quarter minted by the wrong mint press arangement. But how this could happen is an interesting question. I wonder if a coin could be heated to a temperature where the pure copper core melts but the outer copper/nickel doesn't? Edited by toast 03/15/2006 9:34 pm Report this Post to the Staff

R Michael New Member United States 20 Posts	Posted 03/15/2006 10:07 pm Thanks Toast for the response. As for the heating and melting of copper center wouldn't that also deform or destroy the knurling? I know the scan doesn't show too well the distinct ridges on the copper center. Here is a scan showing the face. Thanks again Mike Image: 1-4face.jpg 95.32 KB Report this Post to the Staff
Susanlynn9 Forum Mom United States 5877 Posts	Posted 03/15/2006 10:49 pm Hello Michael and welcome to our CC family! My initial feeling on this is that it's a Mint error. I seem to remember seeing something similar to this before but can't remember what had caused it. I have looked through the Price Guide to Mint Errors book and can't find anything that describes this. Hopefully, someone more familiar with errors will post soon. Report this Post to the Staff

Sap Moderator Australia 16845 Posts	Posted 03/16/2006 01:53 am It sure looks peculiar. My money would be on something chemical, say a nice long soak in a weak acid, to take out the copper and leave the cupronickel intact. Have any of our "coin cleaning experimenters" seen this sort of effect in their experiments? The only other thing I can think of is it's a counterfeit. But why would anyone go to that much trouble to make a fake quarter? Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis Report this Post to the Staff
Bryan1315 Bedrock of the Community United States 14454 Posts	Posted 03/16/2006 06:14 am I was thinking that also until he said it still has the reeding on the copper, it just looks like it has shrunk Report this Post to the Staff
R Michael New Member United States 20 Posts	Posted 03/16/2006 4:06 pm Thank you all for the warm welcome and the time you have taken to post replies. I am not a collecter though I still have my modest collection from childhood, and I am not knowledgeable in this area at all. My take on this is that it is not conterfiet, nor has it been acid treated. It is a normal quarter other than the copper center. I know I am very curious as to what I have and am looking forward to finding out. Thanks again. Mike Report this Post to the Staff
R Michael New Member United States 20 Posts	Posted 03/18/2006 10:39 pm I am wondering if anyone else has any thoughts about this coin. Would it be wise or even worth it to take it to someone that can put his "hands" on it to get an opinion if it a legitimate coin error? If it is what would this be worth, relitivly speaking? thanks again. Mike Report this Post to the Staff
Metalman Pillar of the Community United States 7123 Posts	Posted 03/18/2006 11:19 pm Hi Mike Welcome to the forum !! My opinion !! Something that remains unanswered, due to the relitive distance that we have here ,, would be worth having examined by a specialist, or at the minimum getting good clear pics to someone or organisation such as coneca. http://conecaonline.org/content/icg...butions.html I have seen similar foreign coins(Hong Kong Dollar) and I also recall the same conversation as Susan but cannot remember if an answer was even established as a fact for what may have been the cause.

GREENHORN New Member United States 7 Posts	Posted 03/20/2006 7:11 pm hi mike, a newbie here. just wanted to add, my father was a metalugist so I picked up a little chit chat off and on. I recall copper having a high melting point, and the silver clad would go way before the copper core. so my guess is that it was not a heat theory as suggested earlier. thats just my opinion though, kevin Report this Post to the Staff
R Michael New Member United States 20 Posts	Posted 03/20/2006 8:33 pm well an update. I received a response from Mr Wiles today. He stated that while he isn't sure how it happened he is quite sure it is not from the minting procces. So I guess I can only speculate at this time how it may have come about, especially since the reeding on the copper is still intact so it indicates it is not a wear or filing issue. I would still look forward to possible answers. Thanks again, Mike Report this Post to the Staff
Bryan1315 Bedrock of the Community United States 14454 Posts	Posted 03/20/2006 9:04 pm Well I wish I could answer this question because it puzzles how it happened also because you can clearly see the reeding on the copper part in the last picture you posted and I just dont know what would cause it Report this Post to the Staff
coppercoins Pillar of the Community United States 7629 Posts	Posted 03/27/2006 03:57 am Looks to me like this coin is the result of some sort of Encased Coin. A metal ring is placed around the coin and minted with a design. The process of minting the ring makes it epand into the edge of the coin to grip it and hold it in place. Some of them aren't very tight and fall out over time. Not completely sure about this, but it's probably one of the more plausible answers yet. Report this Post to the Staff
