In 1991 the London Bullion Market Association granted accreditation to the Australian Gold Refineries Kalgoorlie Plant to produce 400 ounce gold bars. This is the first one produced (it is real) hence the K00001 serial number. It is worth $6-700,000 in gold value but really worth several million as it is the first bar produced. It is kept in a very secure vault that is open during the day.
