I included this "Supposed" mint errors for all the auctions that claim a coin has a mint error. And for people who don't realize that these, and coins like them, are not mint errors.
It's apparent that online auction sellers search through rolls of modern coins, and when they find the slightest die crack, or contact mark that might look like a number or letter, or Machine Doubling, or anything that they feel is out-of-the-ordinary for that series, these sellers put it up for auction at ebay.
These sellers try to create hype and cash in on previous of hype of other modern mint errors like the No Edge Lettering, Washington Presidential Dollar. At one point, the No Edge Lettering dollars, where all the rage and sold in excess of $1,000, but now can be had for around $100. So it's important not to get caught up in the hype, and to make sure that what your bidding on is a mint error, and a mint error that will hold it's value in the future.
I received a lot of emails asking about upside down edge lettering on the Presidential Dollars. At first, it was hype as a mint error but it's not a mint error. It's a fact that when the coins are fed into the Edge Letter Machine they can be obverse up or obverse down. So, Upside Down Edge Lettering isn't rare as around 50% of the entire coin's mintage can be in this position, called Position B, while normal position is called Position A.
Above is an authentic, waffled, U.S. Coin, and it was waffled at the mint because it didn't meet their specifications. All waffled coins are damaged coin and they are shipped to a company that melts them down to recycle the metal.
