I have come into possession of a 1963 unopened bottle of canadian masterpiece whiskey. It has bottle stamps from both cancada and america on it with numbers and the year 1963. It came in a red box and is in EXCELLENT condition. It says on the bottle that it is a product of Calvert of Canada LTD. The back label has another set of numbers and says it is imported from calvert Distillers. I am hoping someone can help me figure out the value of this whiskey and some information about it. I have been trying to find out information on it, but have not been successful yet. Any help would be greatly appreciated.
