Check out the edge of this Ike dollar. Can you tell me if this is an error? I believe it is and I think I have diagnosed what kind of error it is, but I want to see if you all agree! I will reveal my thoughts after a few replies. Let the games begin! Ha!
To me it looks like copper was pulled/pushed up from the edge (by the collar?) and then struck into the coin. I have no idea how that could happen or what it's called. The reeding is not fully formed there, just below the rim. What does the edge look like there, in a more straight on pic?
Very interesting. Not sure I am familiar with that specific error type or what would cause it. Could someone send a link or an error ref article about it? Couldn't find much on my own. This is what I was thinking. I thought it was three separate struck-in rim burrs. Apparently these form when there is a chip in the rim of the blanking die, causing a vertical projection of metal from the rim, which can later get folded and struck into the coin. Perhaps I am mistaken! Interested to see what @paddyman98 and the others say. I can send some rim photos shortly.
Yeah, I don't know anything about this stuff, just what I've seen on forums. My first thought was some sort of "struck through rim fragments" but tiny ones. Then in your third image noted that the reeding is only formed for about 3/4 of the width. "Defective planchet" seems too generalized an answer. I don't think I've heard of chips in the rim of the blanking die - would they get obliterated by the upsetting mill? (Machine forming the rim on the planchet)
I like the rim fragment or burr theory. It's good to figure out these things for those interested but the majority wants to know the " how much added value". I would think none.
I agree that "defective planchet" seems like an umbrella term for a multitude of planchet errors. I have never personally seen it used in this context, so I'm interested in seeing what @paddyman98 and @Collecting Nut mean by that diagnosis. I read in another source that it may not be chips in the rim of the blanking die but rather the rim of the blanking die gets worn down, thus the blank is slightly connected to the stock after blanking, i.e. "hanging on by a thread," the thread being the vertical projection / rim burr that eventually get folded and struck in. Maybe that counts as "defective planchet"? I tend to not be so worried with that aspect of things. I'm more so trying to deepen my understanding. Occasionally when I find something more cool I'm curious just so I know where it stands, but knowing the value is not my priority.
I can understand how that falls under the "defective planchet" umbrella. However, I'm having trouble visualizing how such burrs would survive the upsetting mill. Did you ever get a straight on image of the edge?
It’s a clad coin and from your photos it looks as if the outer layer peeled away in the areas on the rim that copper is showing. From the photos I can’t tell if yours is a type 1 or type 2.
This is a very good question, and definitely not one I am familiar enough with upsetting mill process to answer. In the new pics, it looks like the reeding actually goes the full width of the rim, right? Thank you for elaborating! It's a good theory, but if you look closely in the second image in the original post you'll see the copper is actually over the outer clad layer. Very bizarre.
I'll give it another night to see if Paddy has some more speculation, otherwise I may repost it under a new title that may capture the attention of anyone who is familiar with defective planchets or stuck in rim-burrs.
Here is a video with a graphic showing how the upsetting mill puts a rim on the planchet. I can't see how a burr survives that. Maybe?
Thank you for sharing the video. That is quite interesting. I would think that perhaps this is where a rim burr would get folded over onto the surface of the coin since the coin's edges enter that thin slot in the upsetting mill? Perhaps this is a reasonable explanation for the folding? As I'm typing this I thought to check Error Ref's explanation: "When the blank is sent through the upset mill, the burr is folded over onto the planchet. The burr is eventually struck into the planchet." From https://www.error-ref.com/_blanking_burr_/ I can't say the images of confirmed burrs I've seen totally resemble this coin. The mystery continues....
Some bank coin counters ( many years ago) would use mechanical "arms" to separate and feed specific size coins into the "counters" and sometimes the large halfs and dollar would get scratches and rubs across the rims and surface. The bank didn't care as a half was only worth a half to them. Same with the dollar. I was on their board for 3 years before a larger bank bought them out. I did get a good deal leaving that I could soon buy my house. I still bank there
