The value of an old U.S. Treasury note or other form of paper currency depends on its age, condition, and prevalence. In general, older notes of scarce denominations that are in very good or extremely good condition are worth more than newer notes that have been widely circulated and are worse for wear.
If you collect U.S. Treasury notes and are curious to find out how much they are worth today, there are charts on the internet that can help you find ballpark estimates. To find out what you can expect to be paid for your notes and to have other currencies appraised, you should visit a paper money and coin dealer.
