I've heard about the big Aladdin silver medal but don't have one, Jim. I'd say it's worth in the $15-50 range, depending on how big it is (silver value) and condition. I'd be interested if you are able to pick one up.

I looked again and see it's a US Bicentennial item. SteveP would surely know more about this an how scarce it is. Particularly if it's an error medal misspelling "Majesty" [g].
