This exceptional $10 National Bank Note from The Security National Bank of Dallas, Texas, Charter #10564, represents a significant piece of Texas financial history from one of the state’s most important banking institutions. The Security National Bank of Dallas received its charter in 1906, establishing itself during a transformative period when Dallas was rapidly evolving from a frontier town into a major commercial and financial hub of the Southwest. As one of Dallas’s prominent National Banks, it played a crucial role in financing the city’s explosive growth in oil, cotton, manufacturing, and real estate during the early 20th century. This Series of 1902 note features the portrait of President William McKinley and displays the characteristic blue Treasury seal that distinguished National Currency of this era. The visible signatures of bank officials, including what appears to be the cashier’s signature, add authenticity and personal connection to the individuals who managed this institution over a century ago. With serial number 59318 and the distinctive charter number 10564, this note serves as a tangible link to Dallas’s banking heritage and the decentralized currency system that allowed local banks across America to issue their own notes backed by U.S. government bonds, a practice that ended with the standardization of currency under the Federal Reserve System.
