The Great Britain penny is very common, even in UNC and has minimal value. The Bermuda Crown is pretty common, but it is .500 silver (about $7 worth), not real sure but I think top end numismatic value would be about $10-12. The Hawaiian medal I have no real idea about but generally a dealer in exonumia would be asking $3-10 for something like that, and as it seems pretty generic, I would say $3-5. However, value is what someone will pay for it, and any of these items could go higher than my guesses.
