In 1880, the US Mint struck 3,955 Proof and 16,000 Mint State Shield Nickels. Interestingly, those numbers represent the second-highest mintage ofthe series for Proof coins, and the lowest mintage of the series for circulation issue pieces.

Although they had a higher mintage, the Mint State coins fetch a far bigger premium in today's marketplace. For example, just this January an NGCAU 55 example sold for nearly $4,000 while an NGC PF 66★ brought only $1,020 in the same auction.

Due to the extremely large price difference between the Mint State and Proof coins, as well as between this date and other dates, NGC graders mustremain extremely vigilant in looking for counterfeits and alterations.

Recently, a Mint State example of this rare coin was submitted by a collector for certification.

Unfortunately for the submitter, the coin they sent in was not a genuine 1880 Shield Nickel.

At first glance, the coin already looks concerning. The surfaces have clearly been altered as they have an odd matte-like appearance with noluster. That alone would immediately raise the suspicions of the grader that perhaps this is a Proof altered to appear Mint State.

However, that is not the case. Instead, take a closer look at the date.

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 digit was likely formed by a forger using the metal that was there from a previous digit. Looking at the mintage figures, it seems verylikely that the coin was originally dated 1882 or 1883 as those coins had mintages of 11.4 million and 1.4 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-4 values ofthe 1882 and 1883 issues at $25, whereas the 1880 in the same grade is $1,500!

It is possible that the counterfeiter had to alter the entire surfaces of this coin to make his efforts to change the date less obvious. Still,this coin was not a particularly well-done alteration. It was clearly deceptive enough, however, to slip by at least one collector. This is why it isimportant to always closely inspect the date or mintmark on rare dates or date-and-mintmark combinations.
