In the spring of 2007 in upstate New York, reverse design that was intended for coinage beginning in the year 1989. The 1989 reverse is referred to as RDV-006. This is the newest transitional variety discovery.
A subtle but unmistakable change in font in the designer's initials is the most distinguishing characteristic of the 1988 RDV-006. Looking under modest magnification for the flared "G" in the designers initials is the easiest method of identification of this transitional mule.

The variety coin was made with a reverse die featuring enhancements including serifs at the top and the bottom of the right vertical leg of the "G" in the designer's initials.
An article in Coin World's Collector's Clearinghouse followed the announcement on the varietyvista.com website about the existence of Mr. Snow's historic find.

With an average rate of less than one per month of this 20 year-old variety turning up it appears to be exceedingly rare but by no means impossible to find in circulation. The finest known example has been attributed by CONECA and authenticated/graded and encapsulated by ICG as MS64RD.
