What is the value of a 1929 US 50 dollar bill?

Series 1929 US bills were issued as a now-unusual form of paper money called National Currency. They were printed in two forms:

• Bills issued as Federal Reserve Notes have the Words "Federal Reserve Bank" and the name of the district city to the left of the portrait.
• Bills issued as National Bank Notes have the Words "National Bank" and the name of the issuing bank to the left of the portrait. In addition, the issuing bank's ID number is printed in heavy black type on the left and right edges of the bill.

If your bill is a Federal Reserve Note please see the question "What is the value of a 1929 US 50 dollar Federal Reserve Note?"

If your bill is a National Bank Note it may be best to have it evaluated in person by a currency expert, because there were many hundreds of different possible issuing banks. While this site attempts to provide the best answers possible, the sheer number of distinct National Bank Notes makes a sight-unseen online evaluation extremely difficult.
