Old Money is a broad term and I could spend a considerable time discussing what old money has real value. Rather than defining old money value, I would turn it around and discuss old money with little to no worth over face value. There are many notes that, while old are not rare and value is partially driven by rarity (and demand). So even if you have old money that doesn't circulate anymore it doesn't automatically mean the note is valuable. So, below are a list of United States bank notes that have little to no collector value. If your note is not on this list there is a good chance there is some value to it. One final caveat, while the notes below are not valuable generally there can be exceptions. If your note has a serial number lower than 1000 or is all solids like 77777777 these sorts of numbers are collected regardless of the bill so these are valuable. If you think you have a note with a cool serial number it's likely to have some value. Another caveat, these notes below in singles form are not valuable but if they come in a pack that adds value. Currency in packs are worth something so contact me if you have a pack and I can evalulate it for you. If you are interested in knowing about the value of your old money please contact me.
