Clad layer

We were out working away from home and stopped at a store. My friend got some change back and we was looking thru all of it once we were outside. I noticed a quarter he got back had a funny ring to it when it was dropped in the other change. I looked and noticed it looked like it only had half a clad layer. He sent it home with me for more investigation. Is it possible for only half a clad layer to be missing?Polish_20210817_180751909.jpg.c088f4d33914cf450554bcd8a249b7db.jpgPolish_20210817_180648591.thumb.jpg.058ab228c8f9e0cb52e845d9c2fe4a90.jpg

Ohh-kay,... now what? You were short-changed. You were robbed!  I would set it aside...

Be a good one to put in a flip if its the real deal. The weight is what has me wondering.

Anyone know if this coin lies within the "tolerance limits" as mentioned in a similar, older thread for heavyweights?

Looks like it has a lot of potential to be a legit missing clad layer error.  It even has some strike weakness, which would be expected from a thinner coin.  Based on the pics, I think you have a winner.

Yes, it is possible to have a clad layer missing on one side. Colour looks like it may be copper showing  and not ED.

Can’t be 100% sure from a photo but certainly worth getting checked out.

I agree. I have seen a few for sale recently slabbed with only a single side missing the clad. It sure looks like it has a lot of potential. Good find.

Tolerance is .227, so the acceptable average weight is 5.44 to 5.90, rounded to two decimal places.

A clad layer weighs about .91 grams so a quarter missing a clad layer would weigh 4.76 grams.  When you make allowance for tolerance a weight of 4.62 grams fits very nicely for a missing clad layer coin.  I would say it's the real deal.

Thank you all for the replies. I told him about all the replies. He is very happy. I kinda figured it was the real deal when i was inspecting it. Due to the look and weight. Also the ring it makes when it lightly bumps other change. We couldnt match the sound with a regular clad coin. Thank you friends.

Single sided is the NORMAL way to find missing clad layers. Why would both sides be missing? When I see both missing, I am instantly suspicious.

I just didnt know much about them. I didnt know exactly how the clad layer is put on them. And how the cause would come about. I think im gonna do some research on it and try to learn the exact process.

I Would love to hear from @cladkingweigh in on this. I've got a feeling, if anyone knows, he knows.  I know no one more passionate of these underappreciared innovations than he does.   🐓

Clad king has posted quite a bit here and on other sites regarding clad coinage.  He is very knowledgeable of the availability/survivability of high grade examples, and is a great resource.  However I can't recall him posting much, if anything, on error coins.

Why do you you think he would be a better error resource than conder or vkurt? 

BTW - I thought conder's post had excellent information.

I am NOT much of a source for errors. I just recall most of what I have read. I don’t remember where or who as much as what I read. This really cranks up the “link please” crowd. I don’t care. It’s like my career as an election administrator. I write things and people ask me the source. “I am the stinking source. I was there and did it. Most of the best knowledge ain’t on the Internet.”

Clad coins are only sampled for weight, so under- and overweight coins are not unusual. The bulk coinage stock is supplied in large rolls so a manufacturing defect might go unnoticed at the mint.

@Oldhoopster

I had a feeling that was you peering over my shoulder.  Dena's watching too, so I will be cautious in my words...

 Simply put, you go to the source. There is no way you see 🐓, , and not think, Q.A.; likewise one cannot be tempted to think basketball and not consider @oldhoopser.

Twenty-four reples have been elicited; I accept some and gloss over others. Now I would like to hear from @cladking.  If he claims "errors" are not his area of expertise, so be it.  Personally, I fail to see how this could have happened.  I am not interested in WHAT happend;  I want know WHY.  P.S. This is not to impugn the replies of others. (However, my only "complaint," however  unremarkable it may appear be is: I WOULD HAVE LIKED TO SEE THE EDGE.  After all, wasn't that the point of the posting?

I didnt know exactly how the clad layer is put on them.

There have been two different methods.  Both involved three ingots of metal, the two outer CuNi layers and the copper center.  In both cases the surfaces of the ingots that would be in contact with each other would be ground flat and smooth the idea being that the surfaces should be in as close contact with each other as possible no irregularities, no bumps, no voids.  Originally the ingots would then be bonded together using explosive bonding.  Explosives would be placed top and bottom and detonated with the force of the explosion welding the pieces of metal together and then the welded ingot would then be rolled into strip. This was one of the reasons the clad material was chosen.  It was an anticounterfeiting feature.  It was felt that counterfeiters would not be able to do the explosive bonding.

Later rather than using explosive they just used very high pressure rolling to bond the three layers together and then to roll it on out into strip.

If you google explosive bonding or explosive welding you can find some good explanations and a couple of videos that demonstrate the technique.

I'm guessing @Conder101 is right as is typical.  

The high grade of the coin may be simply that it won't pass as "genuine" in coin acceptors.  It has spent a lot of time out of circulation.
