50 Cents - Elizabeth II Ravenclaw

Ravenclaw is one of four houses depicted across a set of Harry Potter–themed coins issued by the Cook Islands in 2021, produced under license from Warner Bros. Entertainment. The gold-plated iron composition places this firmly in the novelty collectible category rather than the bullion or numismatic mainstream — the Cook Islands has issued hundreds of similar licensed pieces, leveraging its monetary authority as a vehicle for the global collector gift market.
