How do you find the value of old currency bills?

Determine the value of your old paper currency online through Coinsite.com or OldCurrencyValues.com. While CoinSite.com specializes in the valuation of currency printed after 1927, OldCurrencyValues.com provides pricing for currency dating back to the Civil War era.

In discovering the worth of old paper currency, first examine the paper notes with respect to the Grading Key and How To Grade Currency links found at either site to determine the condition of the bills. Since many variations can exist for a given year, and some may be much more common than others, reference the price guide and take note of the series, seal colors and serial numbers, which may affect the value of the currency considerably.
