1. Condition: The overall condition of the note is crucial. A note in uncirculated condition (i.e., never been used in circulation) is more valuable than one that is circulated or has damage, tears, or folds.
2. Rarity: The rarity of a particular series and denomination can also impact its value. Some series and denominations are rarer than others, making them more sought after by collectors and potentially increasing their value.
3. Signature Combination: The combination of signatures on the note can affect its value. Some signature combinations are rarer than others, and notes with certain combinations may be more desirable to collectors.
4. Serial Numbers: The serial numbers on the note can also play a role in its value. Certain serial numbers, such as sequential numbers, low numbers, or special patterns, can make a note more valuable.
5. Errors: Notes with printing errors or other defects can sometimes be more valuable than regular notes, especially if the errors are significant or unusual.
