Paper money really does have a value. First of all they are unique (yes I know they have been counterfeited a million and one times).They come with certain security features and plus they really are the image and richness of a nation. They can tell a lot about the history of a country and its politics. But that is not the only reason why you should work hard and earn as much as possible or why you should be collecting today’s currency for your grandchildren. Sure paper money collecting can be carried out as an innocent hobby but it is more than that.
Paper money value just like coins is backed up by its value to the US dollar which in turn is pegged on the value of gold. Additionally coins have value based on the material used to produce them. Paper money collecting can be fun and valuable too, may be not for you but may be your children or grandchildren. Paper money with significant historical value can fetch more in trade or as collector items. For example confederate paper money will fetch a good sum at this time. The better the condition of the paper money the more it will fetch. You can refer to a catalogue of world paper money and decide on what you want to collect and start your own collection. US mint paper money, Canadian paper money collection or Chinese paper money collection, the choice is yours.
So the next time you travel don’t forget to keep some paper money for your collection.
