Altered Date Shield Nickel Article Update
Janell Armstrong of Certified Collectibles Group writes:

As you can see, the "0" in the date looks much smaller and has a different surface texture than the other three digits. This is due to the factthat the counterfeit date was likely accomplished by a forger using the metal that was there from the original date. Looking atthe mintage figures, it seems very likely that the coin may have originally been dated 1882, 1883, or even 1870 as those coins hadmintages of 11.4 million, 1.4 million and 4.8 million, respectively.

Clearly, this would be a profitable endeavor for a counterfeiter, as the Guide Book of United States Coins (the Red Book) lists the G-4values of the 1870, 1882 and 1883 issues at $25 to $30, whereas the 1880 in the same grade is $1,500!
