I have just started collecting paper currency and I am getting some nice notes. Error notes are my favorite type of notes there are. I like error notes because other notes are not as exciting as error notes and error notes are exciting and much more fun to have than normal notes. People like error bills because their rare and collectable. Error notes are all completely different and they are also unique in so many ways. One of the error notes I got was an $1 dollar bill off-center cut and an off-center strike. I bought it for $10. The price normally ranges from $2 to $600 (on eBay) which proves that they can range differentely in price. There are trillions of possible types of error notes possible. People who collect error notes also collect notes that have strange cerial numbers such as 000000001.
