Frequent Doubling In 40% Kennedy Halves?

Many of these are pretty darn obvious, and though I recently learned (through this forum ;-) ) that doubling does not command a premium, it seems like a REALLY high rate of Machine Doubling. Did the mint have trouble with this coin? Was it a result of the new 40% silver composition?

I understand the difference between doubling and doubled dies. That was not the question, but I appreciate the response. Perhaps if I put it simpler...

I am just curious if this coin was more prone to Machine Doubling (whether because of silver material, etc...). The rate at which I am finding these is much more than any other circulated coin denom.

Well, I guess I should have known that help is difficult to come by if you are a new collector... instead of help or opinion, I merely got a curt comment on how much I did not know from one who seems to be a typically unpleasant poster.

I will do the research myself and no longer frequent this forum as my interests are clearly too simple, uneducated, and uninteresting for this forum.

I'm figuring your comments have to be about me since I am the only one who replied.

First off, I don't know how you saw my reply as being a "curt comment" - I replied to the post in as educative a manner as anyone could. I am seen as "unpleasant" because I am to the point and don't have any shyness about telling people that they've found a coin considered a non-collectible non-error non-premium value coin. If that makes me undesirable, then perhaps you and others might want to seek education where people will lie to you and get your hopes up that what you have found is worth something it is not.

I did specifically answer your question by stating, " Machine Doubling is the "shelf" doubling you describe and is not worth a premium value. It is very common, and in some years of some denominations is actually difficult to avoid."

I cannot specify that this is the case with 40% silver Kennedy half dollars because I do not search them or collect them. I was making a general statement about all coins in that Machine Doubling is very common in certain areas of any series. The Mercury dime series is loaded with them. Lincoln cents are very notorious with Machine Doubling from 1955-1958, then from 1968-1971. Nobody knows the specific answer as to why, it's a simple observation.

I simply do not understand why my posts are being seen as non-helpful...I answer the questions. I'm not going to waste your time and mine telling you your coins are worth anything they aren't, and I'm not going to lie to you, even if that would make you feel better about my response.

But the question was specifically asking if Machine Doubling was unusually common in the 40% Ag Kennedy halves. I personally don't know, but I imagine it was either unusually common, or the source of OP's coins was from someone who seemed to want to collect them.

When I read the OP's post, I thought it was very clear that they understood the difference between Machine Doubling and Double Die and the OP already understood that what they had were Machine Doubled Kennedy halves.

the.silver.standard, I, like you am a "newbie", and make many mistakes, many due to "semantics". There is a difference between "hub-doubling, hub-doubled doubling, Mechanical Doubling, and manyy other types of "doubling", and not all are the same. It took me a while to learn the difference between "Hub-doubling", and shelf, Mechanical Doubling. It "looks a lot alike, but that is as far as it goes. Just like looking at "fools gold, and gold. One is a metal, that when hit, flattens, the other will break into blavk dust. It is known as Iron-pyrites, and looks just like gold. The case with a doubled-die, as opposed to a shelf, or mechanixcal doubling, is very apparent, after one gets used to seing it. We all went thru this same stage, and most of the newcomers, will too. There was no "curtness" in Chucks post. Quiet the contrary. He is a very well informed young man with a wealth of knowledge in the cent varieties, among others. You are new, and will get your turn, later as you continue. Be glad you weren't greeted by being called a "liar" with less that two hours on board! I was! I got even, too. I called him a cheater. He usually waits a couple weeks before jumping on someone, (they say). Don't give up so easily. It is all in fun, no matter what is said, "as long as they say it with a smile"!
