Where on earth did you come up with that information? A planchet starts out rectangular in cross section. When it goes through the upsetter to add the rim it comes out looking like a very tall capital letter "I". At no point in the process does it ever have bevelled edges.
Could you please tell me Mike were you got this kind of information from on the internet or other sources ,i would like to gather more knowledge on these types of striking errors if there considered errors. Thank you very much Jazzcoins Joe
Photos of the slots in the upsetting mill show them to be V-shaped in vertical cross section. The bottom of the V is truncated (flat). Now it's clear from examining a large sample of planchets that the shape of the bottom of the slot varies slightly from year to year, mill to mill, and perhaps, slot to slot. The edge of a dime planchet varies from nearly flat (with only a slight bevel extending out from the highest point on the proto-rim) to extremely beveled. Slot shape also appears to differ from denomination to denomination. Dimes show the most bevel overall; nickels show the least, with many showing no bevel whatsoever.
I have, and don't see what you are describing. Show some of yours, why don't you? The purpose of upsetting is to raise a rim on the blank to make a planchet. If a blank is run through a v-shaped shaper, where does the rim come from? Photos tell the tale, but you haven't shared yours. I'm willing to be educated. From CoinWorld http://www.coinworld.com/NewCollector/MintingProcess.asp The upsetting mill consists of a rotating wheel with a groove on its edge. The grooved edge of the wheel fits into a curved section (or shoe) which has a corresponding groove. The distance between the wheel and the shoe gets progressively narrower so that, as the blank is rolled along the groove, a raised rim is formed on both sides of the blank. This raised rim serves several purposes. It sizes and shapes the blank for better feed at the press and it work-hardens the edge to prevent escape of metal between the obverse die and the collar.
Well i just pulled out three rosevelt dime and they don't look any thing like the ops coin Well who has a explaination now. I most have pulled out a hundred of dimes and they don;t look like the ops coin I will post a hundred of these if i have too just let me know OK Jazzcoins Joe
All I can tell you is that I come across dimes with a thin band of reeding between beveled edges every now and again. I just spend them since they are not errors, just a reflection of normal variation in striking pressure and planchet upset. I'll try to dig out a nicely beveled planchet some time in the next few days.
Well I know this coin is not a partial collar that's obvious now. I think this coin was tampered with outside the mint to get this apperance ,they had a way to scrap the edge off the dime maybe held in a vise or something who knows. . I just want to say i have never come across a beveled coin since Iv'e been collecting for 40 years. I WOULD HAVE PUT IT ASIDE IF I THOUGHT IT WAS UNUSUAL THAT'S JUST COMMON SENSE. I know there are individuals out there who will always try to produce some kind of coin that may resemble and error in order to achieve there goal an try and fool others an maybe get big bucks for it. Well that's my finale conclusion on this coin. Jazzcoins joe
Here's a dime with strong upset and a beveled rim/edge junction: And here's an edge-on comparison between a dime planchet with a rather flat edge and one with a strongly beveled edge: The planchet on the bottom is the same one as seen at top.
Mike is 100% correct in his post. I can't find a good image to show of the mill but it is the book. I have a dime planchet that was never struck in front of me. It has the exact same V shape. Thanks for joining in Mike. There is much you could teach us.
If by "worth saving" you're asking if it's worth any money, the answer is no. If instead you're asking if it has any educational value, I'd say it does. But the determination is up to you.
Jazz, go back to my detailed explanation of how the coin was created and read it carefully. I explained why the reeded area would be sticking out further. The center area of the planchet makes contact with the collar first so it is "out further" than the bevel on either side of it. The original pictures only showed one side of the coin but but mentioned that the bevel was on both sides. When he included the pictures of the reverse showing the bevel on that side as well it nailed it.
Learned something from this thread, I never knew that the upset mill had a V shaped groove. I always thought it was just a flat edge against the coin. And I have to say, of all the coins I have looked at over the past 48 years, this dime is the first one I have ever seen with this effect.
