This is a rare, large-size 24mm (approx. 15/16") uniform coat button from the California Transportation Company. Featuring the iconic "C.T. Co." house flag on a lined field, this button was worn on the primary front closure of officer tunics aboard the famous steamships of the Sacramento Delta.

Technical Details:

• Size: 24mm (Coat Size).

• Design: Official house flag with "C.T. Co." initials, "CALIFORNIA TRANSPORTATION CO." lettering, and a rope-twist border.

• Backmark: "SUPERIOR QUALITY" with stars.

• Finish: Silver-toned (Nickel/White Metal).

Historical Significance:

The California Transportation Company operated the premier "Delta Route" between San Francisco and Sacramento. Large coat buttons like this one are significantly harder to find than the smaller cuff versions and are a centerpiece for maritime or California Gold Country collectors.

Refined Dating & Value Note

• Dating: The "Superior Quality" backmark on a white metal base suggests a production date between 1900 and 1920, perfectly placing it during the peak "Golden Age" of the Delta riverboats.
