Re: Once and for all, should cool clashing be a huge collectible?
There is another class of clashed dies that are interesting, Off-center clashed dies: Here is a 1868 Two Cent piece with two off-center clashes, and their arc (from the denticles of a different die) is in different directions! There are examples in the Indian Cent series - in 1880 there is a very big one: The common wisdom… -
Re: Is this Ebay Lincoln what the owner says it is?
<< <i>Looks like we have another ebay "expert" here. There is no Philly Mint BUSINESS strike Lg/Sm date known-just the three proof dies and the Denver business strike. I sure hope no one falls for this one. >> Thanks! So that means the coin pictured is a 1960 Large Date. And who could fall for this? or or or or… -
Re: Help needed-should this 1819/8 bust half go back to NGC for grade review?
Rusted dies leave a microgranular appearance on the coin. Spalled dies, those that are annealed and cooled too fast, and thus overhardened, can spall, or have very small chips of metal fall out of the dies, leaving raised lumps behind. This coin doesn't appear to show either from what I can see. -

Re: Die adjustment strikes.
<< <i>hey errormaven you make good points but never address the topic of the existence of "Die Trial" or Die Adjustment" strikes. does that mean it's your opinion that the Mint simply installs dies and starts striking planchets?? since you seem more knowledgeable about errors than the rest of us, what's your understanding… -
Re: Seriously, why dont they make a square coin?
<< <i> << <i> << <i>Round coins are most efficient from a metal-flow and striking standpoint. They require the least pressure and cause the most distributed stress to the dies. By the way, manhole covers are round for a different reason: that's the only shape you can make them so they do not fall in when rotated. >>… -
Re: Stack's 1798 B30 Dollar Copper "Die Trial" - for serious collectors
In my opinion, if the mint employee was trying to exacerbate the reverse die's cracking issue, would not the imbalance of metal in the press extrapulate a false example of the issue? Aside from the "8" being oddly out of position in relation to the other dies, I would have to agree with PerryHall. -
Re: 1870-CC Quarter on Ebay.
I have no idea why anyone would bid $8,000 on a raw coin like this that could be faked. I am no expert when it comes to Carson City coins, but the surfaces look odd on this piece. At best they have been cleaned. At the worst this is the product of false dies. -
Re: What's the Chance this 1908 Indian Cent is Genuine Double Struck? Help appreciated
Fred is agreeing with Dan, as did I. Perhaps you did not understand what a "vice job" is. It involves making a pair of false dies from two sheets of metal in a vice, turning the coin and squeezing it again to emboss the coin into the impressions made during the first squeeze. -
Re: HELP on value of 1913 british gold sovereign in au
<< <i>To stop or lower the chance of counterfeiting. Subtle details that are easy to pick out to a numismatist. bob >> Normally a counterfeiter will create his false dies using a real coin as a model and some transfer technique such as casting. Any feature on the host coin will be transfered to the counterfeit die.
