Early 20th Century Banknote Security

Early 19th century banknote security was primitive compared to today's security feautures. One of the best methods of stopping forgerers was by using complicated engravings that were near-impossible to replicate exactly, as forgers did not have modern copying or scanning methods.

The paper used was expensive, and only available from one or two manufacturers, furthermore, it was laced with thread, and could contain watermarks.
