Each of the 20 Gram Perth Mint Gold Bars available in this product listing ships in an individually sealed plastic package to protect the bars brand-new condition. The included assay card verifies your purchase, with an individual serial number and assayers signature featured on the card. CertiCard security ink is used on the packaging to ensure you receive the product in its promised condition. CertiCard uses luminescent UV ink to provide a clear signal of tampering when it occurs. If your bar is disturbed inside its packaging, the UV ink is activated and displays a message declaring seal broken. The reverse side of each 20 Gram Perth Mint Gold Bar bears the repeating image of kangaroos hopping across the bar. Arranged in a horizontal pattern, the kangaroos have a deeply-mirrored finish that creates an intriguing contrast between the pattern and the bars background. On the obverse, the Perth Mint logo is featured at the top of the bar. A swan is the centerpiece of the Mints logo, with the words Perth Mint Australia engraved around it. Below the logo, the inscriptions of the bars purity, metal content, and weight are featured. The Perth Mint was founded at the end of the 19th century, and stands today as the oldest operating facility in Australia. Once a part of Englands Royal Mint system in Australia, the Perth Mint is now owned by the state of Western Australia and operates independent of the Royal Australian Mint.
