I've never seen clamshell lamination, so I felt like I had to purchase this coin when I saw it. Please post your own if you have any clamshell lamination coins. I know it's damaged, but when I paid less than $15 for it, it seemed like a reasonable purchase, as submitting a coin would cost me more than that. I had some issues on eBay with the seller (rather the seller claimed to have issues with paypal, but was great with his communication). After giving him time to figure it out, I now have a tracking number, so I feel comfortable posting the seller's photos.
Really? Never? Here is mine - https://www.cointalk.com/threads/25...different-kind-of-lamination-thread-7.300064/
@Seattlite86 The only thing I don't understand is how silver planchet has a clamshell lamination when my clad quarter is obvious. The clad opened up.
Yeah, it is strange. Part of why it appealed to me I'll try to take some good photos of it when it arrives.
Ha.. I do know. There are 2 types of clamshell laminations - First is a Clad issue such as mine where the clad becomes detached from the copper core. Second.. A partially split Planchet such as your silver coin. I have seen a Clamshell Lamination on a solid Nickel.
Photographing this was rather difficult. We don’t have strong lighting in our home. I might try tomorrow for better shots in the sunlight. The splitting is rather pronounced and the reverse is bent backwards because of it. Too bad about the damage, though I doubt I could’ve afforded it if it weren’t details graded.
A "clamshell' silver, copper, or nickel coin is just an advanced version of a lamination - Same cause - improper metal mixture. On the surface, they're laminations. If the improper metal mixture was in the center of the planchet strip, it too will 'laminate', but in the middle of the coin, instead of on the surface. Clad Clamshells are from improper BONDING of the three layers.
Thanks for the breakdown. It’s a very interesting outcome on a coin. I’m happy to add it to my collection.
