Hi guys, Just wondering if anyone has any info on this silver round. It XRF's as pure silver as evidenced by the "1000" mark below the coat of arms. I have only really seen the "1000" designation on some of the European minted silver rounds I have but I 'm not an expert and have no knowledge if countries outside of Europe use that designation for pure silver. Any help or a direction to go in would be appeciated
This is the only thing I could find, it mentions the 1000. https://collection.maas.museum/object/304699. You can ask them questions.
1973 Sydney Opera House Opening Commemorate Medallion search probably under Medallion same design as this without 1000 https://www.ebay.com.au/itm/254362089368
