This silver proof coin commemorates the 100th anniversary of the Golden Pipeline, one of the greatest engineering feats in Australian history.
The region around Kalgoorlie was often short of water, a vital resource to the gold mining industry. The Golden Pipeline was the nickname given to the Goldfields Water Supply Scheme, a 560-kilometre-long pipeline between Perth and Kalgoorlie supplying the precious liquid.
The reverse design of this coin depicts a coloured image of Charles O'Connor, the Chief Engineer of the Golden Pipeline project, with the inscription "Golden Pipeline 100th Anniversary". The image is in the shape of the 'locking bar', a revolutionary Australian technology used to seal pipeline seams without the use of rivets. It sits over a background depicting the signatures of those who attended the 1903 Golden Pipeline inauguration ceremony.
With a limited mintage of just 5,000 coins, the Golden Pipeline 100th Anniversary Silver Proof Coin comes presented in its original grey metal presentation box and is accompanied by a numbered Certificate of Authenticity. A decorative outer sleeve depicting Charles O'Connor is also included.
