Horse spitting a bit is incredibly unbelivably rare error coin. The crack must be something like Karma thing. Ps: @tommcorm, EMT person? That's, Emergency Medical Technican, isn't it? In your other thread, you mentioned 2017P coin. Carry it always in your pocket and have your work friends carry a one cent coin in their pockets. In Medical sector, EMT people are the first at urgency for the "work safety" which has a relation with the one cent coin (talked about this in "coin with/out numeral" thread where I'll also use now your this picture of "spitting horse" at our work of "bit"ting horses...)
Maybe too personal for cointalk, certainly off topic, but I was a student for six months on a two year program. I did well. But I helped save a two year old drowning victim, we got him back but he was under for forty minutes. That ate at me too much. I check on him anonymously on FB still. He can smile. He's five now. But enough of that. I like the coin and the hobby. Thanks for the reply.
The person who makes these posts has his own little thread where he makes cryptic comments. He has started to venture out into other threads. You will get nothing that means anything from him.
I believe the "Spitting Horse" variety only has a die break DOWN from the mouth. IMO, your die break coin is much nicer. I agree with @Kentucky. Have fun.
The spitting horse has a smaller die crack that actually looks like a hose spitting. Yours looks like a bigger die crack. More like a horse that is vomiting. Off topic, I was a Combat Medic in Viet Nam.
Actually, I was thinking of the Morgan Dollar Spitting Horse. You have a quarter spitting horse which is worth around $5.00.
This is certainly on topic. Keywords of this topic: money, coin, horse, error, crack, spitting/vomitting, health. And, you are an Emergency Medical Tech. What caused the spit in this coin? A crack in the die. How a crack happens? Technically, from engineering point of view, a small notch starts a crack and the crack propagates. Guess, where the notch started. In the horse mouth.
ErolGarip, posted: "Emojies and his statement removed in the interests of my posting privileges." Then, we got to the point. "What caused the spit [split?] in this coin? A crack in the die. [YES] How a crack happens? [? many reasons, pick one ?] Technically, from engineering point of view, a small notch starts a crack and the crack propagates. Guess, where the notch started. In the horse mouth. [ Actually, it didn't start in the mouth but it is nice to have an engineer in on the thread. Why do you think it started in the mouth?].
Need to see more of the coin. One end that is visible goes to the rim. As you alluded to, in general, the largest part of the break is the starting point.
I'm not an expert in crack engineering, but, have also mechanical engineering in my background. As far as I remember, the crack starts at the sharp corners/points. A notch is an example on where a crack may start. In this coin with the horse, unless a worker intentionally made a small notch in the die, the probable sharp points in this coin is the horse mouth line which was probably difficult to be made. And, looking at the whole crack line on the coin, it is along the horse mouth line. I don't think that it was a luck or unluck coincidence. Most likely, the crack started at a point in the horse mouth and propagated along the mouth and continued in whole coin.
You know what. The die break on the actual "Spitting Horse" variety DOES START AT THE HORSE'S FACE in a different location. Therefore, I'm going to bet you are the one who is correct! Thanks for sticking to your guns and making me think about what should have been as obvious to me!
Corners, edges?, of the coin may look sharp, but, in their dies, they are smooth round corners. And, the crack isn't in the coin, is in the die. Irregularity in the die is more in inner parts of the coin. Horse mouth part has small "v" like shapes. That bottom tip of "v", a kind of discontinuity in mathematics language, is a potential source for a crack start. We don't have to know rocket engineering. Do you think that it is totally a "random" coincidence that that crack line pass along the horse mouth?
