Rolex Silver and Gold Key Holder

This is a relic from the past. You don't see many business card holders from the Rolex Company dating back to the 40's This case is solid coin silver and weighs 2.5 ounces. The case is in surprisingly great shape for its age and has the obligatory Swiss Made stamp on the back and the silver 800 mark on the inside lid, top left corner. This is a rare piece for a Rolex paraphernalia collector. In the 30+ years that I have been looking I have not seen another one like it.
