High relief & proof silver coins are incredibly popular with discerning numismatists. Because they are struck with a die more times during minting, high-relief silver coins have exceptional depth and overall lustre. Proof coins were traditionally made as samples to test the die. However, today's proof coins are struck in greater numbers using polished dies that give more depth and allow each intricate detail of the design to shine through. Premium quality high relief & proof silver coins are normally struck from .999 or .9999 pure silver and popular examples include the 1oz Kookaburra and the 1oz Kangaroo silver coins from the Perth Mint and the 1oz Zanzibar Vera.
