The small San Diego and Coronado Ferry Collection consists of five items, and documents selected financial operations of the company from early in its long history. It consists of three financial ledgers, one report, and one broadside. The first ledger dates from 1907 to 1916 and includes detailed information on capital, payrolls, expenses, dividends, cash charges, and taxes. Part of this ledger is devoted to bookkeeping for specific jobs and projects, such as "Coronado Turnstile," "Painting the Steamer Ramona," and "New Safety Gates." The second ledger dates from 1920-1935 and is organized much like the first. These ledgers give a clear record of the company's priorities over several owners, and provide useful information on partnerships with local companies for infrastructure, improvements based on customer needs, and problems arising from the company's growth and expansion. This financial picture of the company's activities is supported by a 1924 valuation report which offers considerable detail about revenues and expenditures. The broadside, showing tariffs for bay passage in 1910, documents the transportation habits of people and companies in the growing city.

A third ledger, dating from 1935-1937, documents the financial activities of a partner business, the "Exposition Transportation Company," which existed solely to serve visitors to the California-Pacific Exposition in Balboa Park during those years. It offered luxury and charter bus tours of the city, rollerchairs and rickshaws on the grounds of the Exposition, and transportation to other local stations of transit (including the Ferry Company terminal) for tourists. The ledger details revenue and expenses, taxes, assets, and liabilities of this short-lived but active company.
