1. Condition: The overall condition of the note is crucial. Factors such as tears, folds, creases, stains, and overall wear and tear can significantly affect its value. A note in crisp, uncirculated condition will generally be more valuable than one that is heavily circulated and shows signs of wear.
2. Series and Signature: The series and signature combination of the note can also impact its value. The 1934 $100 Federal Reserve Note was issued in two series: the 1934A and the 1934B. Notes with certain combinations of signatures, such as those signed by specific Federal Reserve Bank presidents and Treasury Secretaries, can be more desirable to collectors and command higher prices.
3. Rarity: The rarity of the particular note can also influence its value. Certain Federal Reserve districts may have issued fewer $100 notes in 1934 compared to others, making notes from those districts more scarce and potentially more valuable.
4. Errors or Misprints: Notes with printing errors or misprints can sometimes be more valuable to collectors. However, it's essential to note that not all errors or misprints increase the value of a note. Only certain types of errors, such as significant misalignments or missing ink, are typically sought after by collectors.
5. Market Demand: The overall demand for 1934 US $100 Federal Reserve Notes in the collectibles market can also influence their value. If there is increased demand for these notes, their prices may rise.
Given these factors, it is difficult to provide a specific value for a 1934 US $100 Federal Reserve Note without examining the actual note and considering its specific condition, series, rarity, and market demand. Consulting a reputable coin or currency dealer or using reputable online resources that specialize in currency values can provide a more accurate assessment of its worth.
