hmm...given that he's probably not exactly perpendicular from the surface of the coin I'd say it's more round than oval
The result of the edges in the pictures provided indicate the two sides got mashed and then someone did in fact flatten it back out, hammer or any possibly the dozens of other tools likely available to flatten it back to its current state. PMD from the evidence provided.
Your last photos are terribly out of focus but it appears to me your quarter does not have any reeding and instead has a smooth, struck edge like a nickel. Is that correct?
Now who's not making any sense good sir? First off: That quarter is round not oval. I would suggest you look at the pics in the first post. Secondly: The reason Im here is to learn more. I can read all the books in the world but they're not going to help me diagnose PMD vs Errors unless I get some practical experience. Thirdly: Where did all that stuff about fake dies come from? are you suggesting maybe it wasn't a hammer, it was some fake die? Fourth: I wasn't entirley disagreeing with you. I was pointing out the reason I initialy ruled out it having been flattened by a hammer, hence the going to try it myself mentality (you know to get some practical experience).
My 2 cents This may help all error hunter new & old. Were not all experts & a new die variety are being found more now then ever. :kewl: http://doubleddie.com/1801.html
Still sticking with my gut that it's PMD. The more I look at it, the more I'm convinced. But.....that's just me.
I thought you may be interested in learning about error coins and gave you some good information about some altered coins to watch out for and hopefully avoid. Since you live in Canada I don't think you understood a word I wrote because our way of thinking is so much different . What I said about fake dies had nothing to do with the quarter this thread is about. You are right , a good way to learn more about how to identify damaged coins from real mint errors is to experiment with them by yourself. Just be careful and don't smash a finger. LOL
in the old days 50s and 60s when they still let convicts have metal spoons to pass time they would take the spoon and pound it on the edge of the coin and make a ring out it would take hours and hours closer to a year put they were nice rings you couldn't tell it was out of money
I am no expert in errors but I have spent many years around machine shop equipment. If I were to duplicate this coin, I would use a hydraulic press with two knife edged tools to attempt to separate the clad layers. After seeing that it didn't work, I would swap to smooth faced tools and flatten out the mess I just made and hope it would still work in the Coke machine. Guess it did.
Now that's a better explanation of what could have happened to this poor ole quarter than what I came up with. Like you bonbonbelly I have also worked with metal about all my life and even a few years in the steel foundry in. It is about impossible for some folks that don't understand how metal can be manipulated to see what is wrong with things. The way I see it is we don't need to be a guiness to see that something damaged the quarter and someone wanted to fix it back so it could be spent. This thread has really been amusing. LOL
Rascal: Thanks for the heads up on the fake dies. I managed to avoid breaking any fingers this weekend. My quarter didn't turn out. I did however keep researching what could have caused this. My knowledge of the minting process is limited, so while I did learn some stuff, I found I was running around in circles. I got to a point where I didn't feel like reading any more, so continuing my what the heck approach i went to YouTube and searched "quarter, hammer". I found this video... If you watch about 55 seconds in the coin shows similar damage. I think with a little practice and a special jig, this coin could be duplicated. I don't know if this one is. I think the diameter and thickness would be a giveaway would be important factors, as this process clearly changes them. http://www.youtube.com/watch?v=yOWkwUqzqPk&feature=youtube_gdata_player
Maybe they tried to make a ring out of the '65 clad quarter before they realized they should have been using a silver coin.
The only problem with your theory is the reeding is still visible not pounded out as portrayed in the video.
