Hi,
Let me say this about that.:-) There is no disagreement between me and anyone else that this could have been struck on a planchet intended for something else:-) My whole thesis was based upon the thought that the coin was struck on an experimental planchet of some sort.
I am totally in agreement that this thing could have been struck on a planchet intended for something other than a U.S. quarter.
Have Fun,
Bill

In my opinion, it was struck on a nickel planchet. I have a 1959 25C struck on a 5C planchet that looks similar. The weight is just about right for this type of error.

The coin is not pure, elementel nickel because it is not attracted to a magnet. The specific gravity results are consistent with a copper-nickel alloy but do not prove it. The densities of pure copper, pure nickel, and any copper-nickel alloy are close enough that a density test will not effectively discriminate between them. You need an expensive SEM/X-ray analysis for that. However, I am relatively confident that the alloy is copper-nickel.
I'm sure if Bill saw the coin himself he would agree that is is genuine. Diagnosing a quality counterfeit from a photo is hazardous at best.

This is better than reading a mystery novel. I would like to know how TPG service tests in determining which exact type of metal alloy this coin is made of...  |

Mike points out the fact that the coin is not attracted to a magnet and that definitely rules out the pure nickel idea although I was just adding that at the point that I did, since no mention of the magnetic properties of the piece were mentioned.
A cupro-nickel alloy blank or planchet getting between the dies opens up a lot of possibilities as to what it could be but how did it get there:-) I think that will now be the fun thing to figure out.

I can tell you this, I too have to wonder how the TPG'S do figure out the same thing macmercury, I also intend to find out once it is sent in, Mike....I wonder who would be the most precise to send this coin to, for the most factual results?  Edited by Morgans Dad

I would send it to PCGS along with my Coin World article. They're more likely to attach a correct label, but I don't know if they'll use the term "orphan". More likely they'll just put "struck on copper-nickel planchet". Error coin writer and researcher.

Mike, here is mine. As Mike Diamond pointed out, PCGS would be the way to go although it would probably make it into a "genuine" holder. Still authenticated nonetheless.   swcoin.ecrater.com

Dave,
Thanks for placing your coin up in this topic, I can see some similarities, how did you come into this coin, you say it is a nickel Planchet, very nice error,What did the grading company grade it? Mike....

Mike,
It was certified by the now out of business PCI. They gave it an AU55. Looks to be about that in my opinion.

Dave, I believe IMHO you received a very accurate grade, I am wondering what grade PCGS would give this coin, MS?MS+, nice obverse strike, well defined hair details, etc? |

Dave, did PCI label the coin as being struck on a different planchet? That is the most important part of the authentication. Much more important than the grade, in my opinion.

I notice what looks like slight wear in the hairlines as well as slight wear on wings and breast. The only area of concern with me would be the area on the obverse which looks like post mint damage. What would you say that is? I also don't have the coin in hand. swcoin.ecrater.com

Dave, I believe Steve has a very valid point, "the authentication" is vital but while you have asked, the "marks" on the obverse are in my opinion, from the striking procedure, not a natural mark, meaning it is not incuse, or raised, just a possible "mechanical mark" of some sort, possibly from the striking process IMO. I would think it alone would NOT be to terrible for the grade.....IMO, I see many strike issues, as opposed to wear, I would place this coin, marks considered, in the MS60-61 grade.....Mike.... The official, ANA Grading Standards: MS61=..Mint luster may be impaired,and the surface may have clusters of large and small contact marks throughout. Hairlines could be very noticeable. Scuff marks may show as unattractive patches on large areas or major features. Small rim nicks and striking or planchet defects may show, and the quality may be noticeably poor. Eye appeal is somewhat unattractive.Contact marks: May have a few heavy(or numerous light) marks in prime focal and/secondary areas.*Hairlines: May have noticeable patch or continuous hairlining over surfaces.*Luster: May be impaired. *Eye Appeal: Unattractive. |

I could not agree with you more Steve on that point. To answer your question, yes they did. The holder indicates "Struck on 5C planchet". Mike, again, I don't have the coin in hand so I can only state an opinion based on the pictures I see. I could be wrong as they could be strike issues and the such. I would also be much more concerned about what this coin is as opposed to the grade as of right now  swcoin.ecrater.com
