I wouldn't normally pay this much for a Single Ring without a case but it is in such nice condition that I couldn't resist. The high-resolution close-up photos convinced me that I should buy it. There are some spots of tarnish and plate loss but the teeth are in perfect condition, which is seldom the case on many Single Rings that I have seen as they are thinner than the teeth found on later Old Types.
