    Fair enough! I have another question and I mean no disrespect, but do you know how coins are made? Again, not trying to rustle any feathers here. I mean do you know all the steps involved in taking the raw material and turning it into a Kennedy? Also, I feel you won't get a good answer from the Mint and if you're serious about this coin, you're going to have to find a source you can trust to take a look at it for a respected second opinion.

    A) Yup, any grandpa, grandma, mom or dad, son or daughter (if you have kids) will quite readily agree that you know exactly what you're talking about....SMH B) there is no one here who *JUST* posts on message boards. Part of the reason you (and others like you) get so much flack here, is because the serious numismatists that are members here, and other forums, want to make sure that new collectors don't come here and read a ridiculous conversation like this and walk away thinking that every coin they find with some anomaly is a rare and valuable find.

    Challenge accepted!

    My Hypothesis: Your coin was squeezed in a vice, rotated after each squeezed, 5 times to give it 10 sides. Next, because squeezing the coin like that in a vice causes the coin to warp in an vertical direction relational to the orientation of the coin in the vice, it was laid on a flat hard surface and likely hammered with a rubber mallet (or something softer than the coin metal) to flatten the coin back out.


    For all those who don't like the idea of an innocent coin being harmed, turn your head now.

    So in about 45 seconds today, I was able to do this using the process I described above with a vice and rubber mallet. Imagine what I could do with more time. I'm 100% sure that after a try or two more (at the cost of $1) I cold duplicate your "error" exactly, but I've already spent 50 cents too much.

    To address the idea of your half being minted on the foreign planchet from Australia...

    I have 5 of these Australian coins and here's how its 100% impossible for your Kennedy half you have to have been minted on one of these planchets.

    First, your Kennedy half weighs around 11.3 grams (give or take for acceptable tolerances), while the Australian half dollar weighs in at 15.55 grams (again give or take for acceptable tolerances).

    Strike 1!

    Next if you study the size of the two coins, one on top of the other, You will see that the Kennedy half dollar is smaller in diameter than the the Aussie half. Which makes sense because the Aussie half is 31.51 mm and the Kennedy half is 31 millimeters. Along with the Kennedy half being squeezed in a vice, makes the whole thing visibly smaller in diameter. My picture below shows this. The Aussie half on the bottom Kennedy half on top.

    Strike 2!


    Next lets talk about metal composition. While both halves are, indeed, made from copper and nickel, you can see from the side profile pics that they are very different coins when it comes how that composition is constructed. The Aussie half is a solid alloy of 75% copper and 25% nickel, there is no cladding. They mix the metals together roll them out into a big sheet and start punching blanks. The Kennedy half, however, is a clad coin. The coin has a 100% copper core which is sandwiched (bonded) between two layers of a copper and nickel alloy. This is a much more difficult piece of metal to produce and is, for the most part, unique to modern U.S. coinage. So if you look at my pics below you will see that the Aussie half on bottom has a solid gray silver edge while the Kennedy half has three very obviously visible layers to the coin.

    Steeeeeeee-rike 3.... and you're out!


    Your coin was NOT minted on an Australian planchet (or any other foreign planchet for that matter) It was squeezed in a vice and hammered out to be flat after being squeezed.

    Thats a horrible replica. Lol. Well good post. I couldnt make any of mine look like that. Although your edges aren't as even as mine... one could believe that your method would replicate it. How much for your replica? ;)

    This is not true. I've watched these "serious numismatists" run off many posters by insulting them and not coming up with a valid explanation. While I wasn't able to replicate it.... you are the first person who makes replicating this coin possible and offered up a great explanation. :)

    Agreed, but like I said, more time and effort would create one like yours. The trick is to squeeze the coin and make each side the same length. IMO that would take calculation and preparation before hand, but like everything else in life, the more time you put in planning, the better the product.

    I dunno, I've made it a habit to read a lot of the posts you're referring to and its a frame of reference issue. Unfortunately its an artifact of electronic communication these days, but the replies that usually would make someone feel unwelcome or not wanted are usually traced back to the inability of the person replying to the OP to communicate better. A short sentence with in a blunt manner can be construed so many different ways and is typically filtered by the OP with their own feelings and tone, not the repliers. If time is taken to be precise then you get a less harsh message...I think it also comes down to how may times the veteran collector\numismatist, who's been at it for 25+ years, get told by some newbie, who just found a weird coin for the first time, that they they know more than the veteran. Its all in the communication.

    Free! shoot me $20 for shipping and I'll have it on its way to you today! :cool:

    Most of the serious numismatists consider this sort of thing funny. The fact that you would expect the mint to admit that they made an error is priceless. My family has been collecting since the 1870s, but hey what do I know.

    Maybe the people who tried to tell you that you coin was just damaged were simply being genuine. CT is a great forum with many knowledgeable members and some very astute specialists. You came to the correct place for advice, but didn't hear what you wanted too and resorted to trying to defame some those who were trying to tell you the truth. I hope that you can find the answers that you are seeking, but you will need to trust those who are trying to give it to you for that to happen. Good luck sir.

    I have a Conecticut coin that has a very odd finish. I Thought that it could be a fortune. Through the years of collecting and understanding how a coin is made some of the coins that I have found, I hold close because without them I wouldn't have the Knowledge I do now. I wish I knew Everything. Wait I do Just ask me. 99 conecticut obv.jpg 99 conecticut rev.jpg

    Wow that's about as LDS as I've ever seen a state quarter (and my favorite of the designs too). Reminds me more of the early coppers with that texture, keeper anyway.

    Of course. The eye appeal would limit the grade to perhaps 64 or so, but contact marks and wear are the determining factor for grading below that point. If I had to offer a grade, 63 seems about right.

    Not really, sentimental value is better than you're going to get for it despite the unusual nature.
