Bobby / Susan if this needs to be moved to the Error section, than please do so.

Webster defines error as follows: "....something produced by mistake, ...the amount of deviation from a standard or specification, ...a deficiency or imperfection in structure or function, ...a departure from what is true, right, or proper."

With all the hub bub over the edge "errors" on the new Washington dollars, what really constitutes an error coin? I am sure that the Mint defines how a coin should appear after it is processed from a blank to a finished coin, but I also assume that there are acceptable errors / flaws that can be accepted by quality control.

When there are hundreds, probably thousands of coins that contain such errors as upside down lettering, does that reaaly make the coin that much more valuable? Now when there is no lettering or no design on the face of the coin, no that would be an error as it should be caught in quality control.

I guess my question is, when there are a multitude of mistakes / errors made as oppossed to a small percentage made , are these coins realy that much more scarce or valued more?

Almost everything that the mint did not intend is an error. Some Major and many minor.

Upside down edge lettering is NOT an error as the mint intended for the coins to be struck that way.

Blanks are errors as they are unintended,

I would define a numismatic error as a coin "oddity" that is outside of US Mint production tolerances and cannot be traced to the use of a particular die. Examples include off-center, double strike, etc. but not machine/strike doubling or minor die cracks as those would be considered "within tolerance."
Anything traceable to a particular die would be a die variety. Examples include double dies, RPMS, etc.

Is there a document somewhere that tells us what is "within tolerance" when minting? Kind of like looking at a machining drawing that states the tolerance is +- 0.001?

Of course, I do not collect errors, and do not try to figure out which coins are and are not errors, but my view is very simplistic, and certainly not fact per say. I think anything that does not resemble the proof, as I think this is what the coin is supposed to look like, IMO should be an error. I know it's not the case, and there would be more errors than non-errors if it were, but it's just my mindset. This is just my opinion, and NOT fact. Just putting in my Two Cents is all.

That is of course until I can read the tolerances set forth by the minting process.
