Hey everybody, Because proofs are made from specialy made planchets and specialy prepared dies, are there any known errors in the proof realm? I know that older proofs such as from the 1800's may have been more easily exposed to die clashes and errors of the sort so lets keep it 1950 or sooner. I know there is something to do with the 1964 kennedy proof along the lines of more or less strongly struck hair but any other known errors would be much appreciated!:yes: -Ryan
There are alot of them.. Go to Coneca's Master listings and nose around a bit. ( especially look into the Kennedy Half Section )
One of my favorite proof errors (well, it was an error until recently) is the 2005-S KS Silver SQ with the die gouge on the bison. There have only been 12 of these reported, but because the processing of proof coins is supposedly more stringent, I don't know if any more will ever surface. The gouge is very visible to the naked eye. Anyway, I submitted mine to NGC a few years ago, and it was classified as a Mint Error. Since then, however, it was added to the CPG, 5th Edition, Volume II which was released a few months ago. Because it is listed in the CPG as FS-901, I will probably resubmit it to NGC for the designation. I could just leave it as it is, but the NGC Census doesn't separate errors from the normal populations. It isn't every day that you find a "perfect" error, and it would be cool to see it listed as the Top Pop at PF70UCAM with no others. Chris
The "accented hair" 64 Kennedy proof isn't really an error: http://www.ipotad.com/pages/ah2.html At any rate, there are plenty of errors on proof coins - the missing "S" mint mark on Roosevelt dimes immediately comes to mind (lordy how I wish I had them in my Roosie collection!)
Again, not mine: Both, I suspect, were manufactured intentionally and smuggled out but thats simply my opinion.
That is one of the most interesting errors that I have ever seen. The color on the smaller one is just beautiful.
There are a fair number of doubled dies on proof Ikes, there is a strong doubled die 1970-S cent. There are rotated dies etc.
While this is true, I don;t believe that the industry considers a doubled die to be an error as much as it considers it a variety. IMO, a "variety" has the error during the die creation process while a minting "error" occurs during the creation of the coin and as such, could very well be one of a kind. Clips and broadstrikes are possible until you get to the packaging process. Automated or not, if the coin will not fit into the intended packaging due to a broadstrike or major off center strike, you really have to wonder how the coin made it out of the US Mint or packaging facility.
