You may want to rethink that comment: http://www.ringramcoins.com/english_coins_antique_coins_catalogue.shtml
There's some information in the link below about counterfeit pennies. There have been many fakes made of British pennies and according to the article, most of the older ones were made of lead. The other thing to consider is maybe your penny had been plated at one time and it's just the plating that has worn off. http://www.predecimal.com/forged/victorian.htm As to your Korean notes, post a new thread in the paper money section. You'll get more response there.
