Hello! New to the watch world- I have a very unique Corum Coin Watch I inherited.This is a one of a kind $50 double eagle Corum Custom made coin watch. This watch was custom made for the Cargill Family- the note in the box is a hand written from Marion Macmillan Cargill to my relative. It has a large diamond on the crown. I have a certificate and also correspondence from Corum confirming it's rarity and that it was a custom one of a kind watch. Corum did make a limited run of 100- $50 coin watches for their 50th anniversary- my watch was produced in the 1990s. Just had it serviced and the watch runs great. This watch would be a perfect watch for someone who collects Corum, there won't be any other watches like it. Asking $12k.
