William & Mary silver "Tribute to Mary" Medallic Token (c. 1689) AU58 NGC, MI-695-93. Eimer-319var. Sharply struck with some blue iridescent tone in the fields. Struck in copper and silver, the reason for these issues are unknown, but one die combination was speculated as a Pattern in Peck, and given their typical appearance, it's somewhat likely that many were used in the course of commercial exchange.
Estimate: 300-500 USD
