The material in this series consists of two books of canceled stock certificates for the Nevada Bunker Hill and Sullivan Company, 1909-1917, and stock ledgers and journals for the Bunker Hill Company.

The stock ledgers are the official record of stock ownership, recording all changes in holdings, the names and addresses of shareholders, the date of issue, the certificate number, from whom it was received, the number of shares received, the date of cancellation, and to whom it was transferred. These are bound volumes and are arranged alphabetically. The stock journals list changed in stock ownership chronologically.

The ledger and journal for the Oregon based company are for common stock, 1887-1924, and voting trust, 1917-1924, whereas the Delaware company includes common stock, 1924-1927, preferred stock, 1925- 1927, and voting trust stock, 1924-1935.

There are four bound volumes of stock transfer ledgers, 1912-1918, plus another stock ledger for 1910- 1916, but there does not appear to be any relationship between the single volume and the previous four.

Box 66 contains a stock ledger kept on 5x8 cards from 1953 to 1068. Some of these entries correspond to entries in the Common stock transfer journals, others to not.

The nine volumes of common stock transfer journals are in order by folio number, each page being a folio.
