While attention is always directed towards the Holey Dollar, the Colonial Dump is a rarity in its own right. The Dump with the lesser value of fifteen pence circulated widely in the colony: the extreme wear on most Dumps evidence that they saw considerable use.
So while the Dump may seem to be the subservient partner of the Holey Dollar, the reality is that top quality Dumps are extremely rare.
This Colonial Dump has attributes that make it truly memorable. It is a noted piece, acknowledged as one of the absolute finest known: beautifully centred, complete denticles, strong vertical milling and clear evidence of the original Spanish Dollar design.
The denticles and vertical milling were utilized by Governor Macquarie to protect his coins to reduce the chance of paring away a portion of the silver without its loss too obvious. In most examples the denticles are partially obliterated, the milling barely evident. Not so with this Colonial Dump.
Those Colonial Dumps that depict their origins as having been struck from the centre of the Spanish Silver Dollar are highly prized. The parallel lines that run below the Crown on the obverse are the crosses in the shield from the original Spanish Silver Dollar. The castle and the lion’s head; a feature of the Spanish Dollar design also are clear below the Crown.
Furthermore, this Dump clearly shows the name of the person charged with the responsibility of its striking. The H for Henshall on the reverse between the words fifteen and pence is crisp, another aspect that is highly valued. In most Dumps, the H is indistinct, just a blob or not present at all.
