gee_dubya75 Valued Member United States 166 Posts	Posted 07/19/2007 07:34 am I've been searching rolls for 90% and 40% half dollars for about a month now and have come across two 1967 halves that appear to be clad. I know that the 40% will usually have two different silver color bands around the rim of the coin but this coin is really weird. One half the thickness of the coin is silver and the other half is very copper looking. I don't know how well you'll be able to see it in the picture. What are your thoughts?

gatzdon Valued Member United States 280 Posts	Posted 07/19/2007 09:48 am I've found them where the center is showing it's copper color. The center layer is about 80% copper. I've also found them in such good condition you can't discern the layers without a magnifier. I've also found them where the center layer is completely black. I've concluded that I need to look at the face of every coin I go through to assure I'm not overlooking any silver coins or proofs. I think that people who only look at the edges of the coins to go through them faster are missing alot of good finds. Report this Post to the Staff
Conder101 Bedrock of the Community United States 17884 Posts	Posted 07/19/2007 10:22 am I think it is almost certainly 40% silver considering the cuni clad composition for the half dollar was not adopted until four years later, and if the planchets had been punched from quarter strip it would have been much thinner. If they had somehow rolled clad strip to half dollar thickness they would probably have been discovered long ago because a lot more than one would have gotten out. If we want to truly find out, the first step is to check the weight. A 40% silver clad weighs 11.5 grams +/- .4 grams. A clad coin weighs 11.34 grams +/- .45 grams Unfortunately because of the mint tolerances there is an overlap in the weights so weight is inconclusive unless it weighs more than 11.8 grams or less than 11.1 gram. So if it is in the overlap area then you have t run a specific gravity test to know for sure. A 40% silver half has an SP of 9.53, while a clad one would have an SP or 8.92 Report this Post to the Staff
gatzdon Valued Member United States 280 Posts	Posted 07/19/2007 10:31 am Condor, dropping it on a table is a better test. the cupronickel and silver clads have a distinctly different sound. Drop a nickel clad on the table. Drop a silver clad on the table. The difference will jump out at you. Then drop the coin in question and I'll bet it sounds just like the silver clad. Now for the real question, how to make sure it's not a 25% silver error coin http://mikebyers.com/errorskennedyhalves.html (I'm guessing that this coin is just missing one of the clad layers) Edited by gatzdon 07/19/2007 10:33 am Report this Post to the Staff

garylcsr Pillar of the Community United States 1952 Posts	Posted 07/19/2007 3:28 pm my only thought is. why are you holding it like that? I understand that it is circulated but if you are going to keep it why not try to keep it close as you can get to what it was when you got it.i don't use gloves on circulated coin either but I don't hold any coin like that. just in case it turns out to be a good find. one thing is for sure you will be able to identify that coin any time just get finger prints lol.i know to each his own and I am not cutting on you I don't get it. please don't take this as a put down. it is only a question that gets on my mind almost every time I see that but I have never asked before Gary Report this Post to the Staff
gatzdon Valued Member United States 280 Posts	Posted 07/19/2007 5:58 pm Around me, most dealers will only give you junk silver prices for Kennedy half dollars regardless of the condition. It's a scam I know, but as a result, most people around here treat the kennedy silver clads like they are junk silver because they know they will not get more for them. Report this Post to the Staff
gee_dubya75 Valued Member United States 166 Posts	Posted 07/20/2007 06:49 am Gary, To answer your question....mostly because I'm a dufus . I don't take your comment as a cut but rather as a friendly reminder that you should treat every coin as though it were invaluable until you prove otherwise. I'm new to coin collecting and haven't learned that mindset yet. It's interesting, I went back and looked back at a bunch of my 40% halves and I find three distinct types: 1. edge is one consistent silver color 2. edge is two different 'shades' of silver 3. edge is two completely different colors--silver and copper Did they change the composition of the materials used? I don't see any trends like certain years tend to be like #3. Just curious. Thanks for all the good info already. Report this Post to the Staff
