These 1 Oz Australian Gold Kangaroos had been obtained by MintID from the Perth Mint and packaged inside safe cards. The card includes a capsule space for that coin and features a 128-bit encrypted microchip. If tampered with, the microchip “dies” and renders a tampered end in the MintID procedure. https://smart-money-empire.com/product/buy-australian-kangaroo-1-oz-gold-coin/
