2003 Golden Pipeline 1oz Silver Proof Dollar Coin

To commemorate the centenary of the Golden Pipeline, The Perth Mint has released a specially designed silver coin with the support of The National Trust (WA), in which the historic pipeline and its associated infrastructure is vested for heritage conservation purposes.The reverse design of the coin features a coloured image of O'Connor and the inscription GOLDEN PIPELINE 100th ANNIVERSARY. Both appear within the shape of the famous 'locking bar', revolutionary Australian technology used to seal the pipeline's seams without rivets. This element of the design is set against a background of signatures of those who attended the 1903 inauguration ceremony, and the inscription 1903 - 2003. The reverse design also includes The Perth Mint's 'P' mintmark. The 2003-dated coin is struck from 1oz of 99.9% pure silver in proof quality. A limited mintage of only 5,000 individual Golden Pipeline coins have been produced.
