The first set of British India notes were the 'Victoria Portrait' Series issued in denominations of 10, 20, 50, 100, 1000. These were unifaced, carried two language panels and were printed on hand-moulded paper manufactured at the Laverstock Paper Mills (Portals). The security features incorporated the watermark (GOVERNMENT OF INDIA, RUPEES, two signatures and wavy lines), the printed signature and the registration of the notes.

British India Notes facilitated inter-spatial transfer of funds. As a security precaution, notes were cut in half. One set was sent by post. On confirmation of receipt, the other half was despatched by post.

Small Denomination Notes!
The introduction of small denomination notes in India was essentially in the realm of the exigent. Compulsions of the first World War led to the introduction of paper currency of small denominations. Rupee One was introduced on 30th November, 1917 followed by the exotic Rupees Two and Annas Eight. The issuance of these notes was discontinued on 1st January, 1926 on cost benefit considerations. These notes first carried the portrait of King George V and were the precursors of the 'King's Portrait' Series which were to follow.
