There is no such thing as a hologram edition. Any hologram on a US silver eagle is considered by collectors as post mint damage. Because of this, your coin is worth melt value or perhaps a bit more. At the time of writing, it is around $32-33 though it fluctuates based on silver price.
The approximate value of your coin according to Numismatic News Coin Market Monthly Price Guide for March 2007: 1990 Silver Eagle = $18.00

The only reference I can find to a 2007 Australian 1 Dollar coin featuring a Koala is to a pure silver 1 ounce coin with a current value of about $30 AUD. It would probably be suitably packaged in a case.
The term "Silver Dollar" is a widely used [and Misused] term. Is this in fact a coin which says One US Dollar? There are many 'coins' minted today by private firms with as much as 100% silver and since they are not afiliated with the US Treasury, they would not have a mint mark such as you would find on uUS coins in normal [or former] circulation. It is also possible that you have a 'Silver Eagle' which is an authorized US coin. If so, it will have Lady Liberty in a flowing robe, the sun at her feet, and 'In GOD We Trust' to the side. On the back, you should see a bald eagle with 13 stars above his head representing the 13 original colonies, and "One once fine silver One Dollar" printed around the edge. This coin was minted at the US mint in West Point, New York. It is a legal-tender coin, but don't let it go for a dollar! Last time I checked, it was worth over $16.
If you check the back you'll find that you have a halfdollar. There has never been a US-issued Kennedy silver dollar.
