The promissory notes were only as good as the worth of the issuer. Forgeries were common. Many circulated for great lengths of time and often were never presented. This encouraged drawers to use ink that would fade.
In a way, the failure of Governors King (1800 to 1806) and Bligh (1806 - 1808) to stem promissory notes was evidence of the vitality with which private enterprise was growing in the colony.
In 1810, Macquarie, as the new Governor of the penal colony of New South Wales, put forward a plan for a bank as a Government institution. He also requested £5000 of copper currency, low denomination coinage, to curb the use of promissory notes. Both plans, the bank and the copper coin, were rejected.
By way of consolation, Macquarie was sent £10,000 of Spanish silver dollars (40,000 coins) with a request to take the necessary steps to prevent their export.
He secured the retention of the imported dollars by cutting out a circular disc from each coin. The holed dollar and the metal disc that fell out of the hole was over-stamped and transformed into a local, purely over valued coinage. The Holey Dollar and Dump.
A deterrent to their export was their reduced silver content. However to further prevent export, masters of ships were required to enter into a bond of £200 not to carry the coin away.
Anyone counterfeiting holey dollars or dumps were liable to a seven year prison term; the same penalty applied for melting down. Jewellers were said to be particularly suspect.
Macquarie had high hopes for the Holey Dollar and Dump, and in particular the Dump.
He stated that the Dump would fill the role of small change and would remove much of the need for promissory notes of low denominations.
So convinced was he about the efficacy of the low denomination Dump that his proclamation dated 30 September 1813, giving the Holey Dollar and Dump legal tender status, also banned the issue of promissory notes of less than two and sixpence (or the equivalent of two Dumps).
