This MASSIVE silver coin has an equal-but-opposite TINY Mintage! Struck from a WHOPPING TWO KILOGRAMS of 99.99% pure silver, this gargantuan collector coin is limited to just 200 coins worldwide! That means just a lucky few can own this coin. Created by The Perth Mint using their well known concave high relief technique, there has never been a Kookaburra like this Australian Legal Tender, silver giant! Measuring 101mm in diameter, this behemoth also measures 36mm in thickness - that’s 5mm bigger than the diameter of a 50c coin!
