Your large foreign silver coin is a "Maria Theresa Thaler". It most likely wasn't actually struck in 1780; they were a popular "trade coin" in Arabia and East Africa, and various mints around the world issued "restrikes" of these attractive coins up until a few years ago. It is real silver, about 3/4 of an ounce, so it's worth at least that much.
If you post a fairly good (not too blurry) picture we can have a go at identifying the date and mint of issue. Key areas to zoom in on are the "saltires" (the thing that looks like an "X" after the date) and the "arabesques" (the feathery things visible all around the side of the coin). Their exact shape are clues to the coin's true origin.
For Australian coins, while you're waiting to get your hands on a copy of the "Maccas" catalogue, have a look at sites like Cruzi's Coins for a bit of info on Australian coins. If you're aver a "going price" on ebay, just type in the details (eg. "1927 florin") into the "Completed Items" search to see what they've sold for. But condition is everything.
