Is that why they are so cheap, he knows it's not real? He has so many feedback that I believe he's just selling dent or scratch coins to get rid of them. I bought 2, but only 1 came. The mirror proofs looks wavy, not mirror like. The queen's head looks very flat. I never buy Australian coin before and all the auctions looks like that.

It keeps moving between 31 and 32 I used some magnets and it has a bit of a resistance. They all look like that on ebay, am I worrying for nothing?
If you're going to be buying silver from uncertain sources, you really, really ought to get a scale with more precision. You can probably get by with one that goes to the tenth of a gram, but you can get ones pretty cheaply on eBay that weigh to within .01g.
The seller looks pretty legitimate and even if the coin is fake, it is possible the seller doesn't know. After looking at the link you provided though, http://www.silverlunar.com/2012/03/silver-lunar-dragons-fake-vs-real.html, who can say for sure whether it is real or not? With that said, there has not been any clear indication the coin is fake so without some credible evidence that questions the coin's authenticity, I think you may be worrying for nothing.
