Sentence:  Basically, to overcome an acute shortage of money in 1813, Governor Lachlan Macquarie bought silver dollars from Spain and then punched the centres out, thereby producing two coins - the ‘holey dollar' (worth five shillings) and the ‘<WSD>dump</WSD>' (worth one shilling and threepence). Talk about creating money out of nothing—the original silver dollar only cost five shillings! The holey dollar and the <WSD>dump</WSD> have been adopted as the symbol for the Macquarie Bank in Australia. 
Meaning of the word marked with <WSD> tags:  A small coin made by punching a hole in a larger coin (called a holey dollar).
