The 2017 1oz Silver Swan Bullion Coin is the first release in The Perth Mint's Australian Swan silver bullion series. Struck in one troy ounce of .9999 fine silver and issued as Australian legal tender, it introduced the annually changing swan theme in a tightly limited bullion format. The Perth Mint records a maximum mintage of 25,000 and confirms the issue sold out, giving this opening date strong first-year collector significance.
