I'm not quite sure how a silver coin becomes "rusty", but this one did it. Some underlying luster with lots of yellow/gold make this a very attractive example. The letters of Liberty are bold, although the hair is a bit soft. The reverse is primarily toned in shades of rose. Total PCGS AU population is 79 with 36 in AU 58. The BCCS rating is R1. While not part of this set for Everyman purposes I was also fortunate enough to locate a second example of this coin (also in PCGS 58) Broadstruck out of collar, and have included images of it as well.
