green18, im pretty sure that the coin has not seen any grinding (altering). thats what i first thought, but the tapering is uniform all the way around and on both sides.
I say machined. If it weren't beveled, I might say otherwise, but so far as I know a partial collar wouldn't result in a 45 degree surface. Guy~
Cutting a chamfer as shown on both sides of the coin wouldn't be the simpliest thing in the world to do, but I think it could be done. You would need to "machine" a holder using material (aluminum?) larger than the diameter of the coin. Then counterbore a pocket approximately 2/3 the thickness of the coin and maybe ten thousandths less than the diameter (so the coin cound be tapped into place to secure). An ejection pin hole must be drilled thru the holder. Place in a lathe, cut the chamfer, eject the coin and repeat on the other side. This would result in a chamfer that was running perfectly concentric arounding the circumference of the coin. Seems like alot of work to me!
Nothing against you old boy but who, in their right mind, would take the time to cast a counterfeit of a '99D dime?
It is your opinion and you are welcome to it, but I seem to remember a fable about a little boy who cried wolf all the time......................
It's not just an oddity. It's inconsistent with the normal functioning dies which the mint would use. I find this explanation most likely, someone made an average quality counterfeit of this coin and then tried to spend it. It would be very profitable.
Just to be different this time, would you please explain what you are seeing that no one else can see.
I looked at this coin very closely along with another dime under a magnifying glass and it looked completely legit. I could see people conterfeiting dimes in large quantities. Because unlike, let's say a hundred dollar bill, no store clerk is going to examine a dime closely. but that doesn't seem like the case here, well atleest to me
That coin does not look like any railroad rim error I have ever seen. Every single one that I have ever seen, without exception, has a vertical smooth edge. This coin has a double beveled edge. I don't think it is a case of the coin being machined either. This is a clad coin, and the clad layer is very, very thin. Any machining to produce that bevel and the copper would show through. That said, I have no idea how this could have happened. I am going to move the thread, I'll leave a re-direct, to the Error section. Perhaps someone there will have an answer.
Well, remember the Henning nickels back in 1954? He produced over 400,000 of them. Of couse, a nickel bought alot more back then....
