Question About Intentional Errors.

Very broad subject, and as stated above has/would the US Mint ever admit to a falsely created error on a coin by a mint employee.?
You could read up on the history of "Mule Coins". These can sell for $100,000 or more.
There has been noted suspicions about various versions found, but alot have been readily graded by the various TPG companies.
It's a grey area for sure. If the coin has been graded by a quality TPG, that gives it legitimacy right? or does it?

Here's an article on Mike Byers' website which has a brief discussion on intentional errors. It includes a quote by the Managing Editor of Coin World: "Obviously, the marketplace accepts these coins, and some collectors are happy paying thousands of dollars for coins that show every indication of having been created through illegal means."

There is a link in that article for a very interesting interview of Fred Weinberg by Seth Chandler.

Here's another interesting error that I ran across that I have a hard time explaining other than being intentionally made:

Good question Hondo.

Personally as a collector, I see these intentional mint errors same way as post mint damage. That 1972 Ike dollar is definitely post mint damage in my book and although very interesting, I wouldn't pay extra for something that looks like a vise job lol

I cannot have it, but I want it.

I think that, almost by definition, a mint error cannot be intentional. But as anything that comes out of the mint seems to attract collector interest, that seems to be unimportant from a commercial perspective. Intentional "errors" have the potential to be more spectacular, not being limited by the normal processes in a mint.

A number of errors that came out of the Royal Canadian Mint were suspected of being deliberate.
