Found these three items at my local park, which is proving to be a great little producer.The ring is 9 carat and was at a similar depth to the other finds (5 to 6 inches) so Im guessing it also is about a hundred years old. The Sydney cricket ground badge is one of the earliest enamel badges issued and I have to do some more research on its rarity. It also has a name and number engraved on the back. The medal is gilt brass and was issued to celebrate Australia's federation. Love my Xterra 70
