1. Condition: The overall condition of the bill plays a crucial role in determining its value. A bill in pristine condition, with no folds, tears, or stains, will be more valuable than one that is worn or damaged.
2. Rarity: The 1950 Series C $10 bill is relatively scarce, making it more valuable than more common bills. The scarcity is due to the limited number printed and the fact that many were destroyed or withdrawn from circulation over the years.
3. Serial Number: The serial number on the bill can also affect its value. Certain serial numbers, such as low numbers, repeating digits, or sequential numbers, are considered more desirable by collectors and can increase the bill's value.
4. Star Notes: Star notes are $10 bills that have a star symbol (*) next to the serial number. Star notes are considered more collectible and valuable than regular bills.
5. Signatures: The signatures of the Treasury Secretary and Federal Reserve Bank President on the bill can also influence its value. Certain signatures, especially those of well-known or historical figures, can make the bill more valuable to collectors.
Given these factors, the value of a 1950 Series C $10 bill can range from a few hundred to several thousand dollars. It is important to consult with a reputable currency expert or dealer to get an accurate appraisal of the bill's worth.
