I had some perth mint coins listed on trademe, cashing some out to buy a car. I came across some more money and didn't need to sell any more so I put the price up.
I put them up to $100 per oz. Said In the comments that I didn't need to sell them, but was happy to part with them at $100/oz as that was the intrinsic value I saw in silver, that if price manipulation were to end tomorrow $100 would be a bargain.
The bastards removed my add and emailed me to complain the add was not genuine. Guess Trademe is a tad over policed. Guess its better than ebay and the german/tibettan/100mills rubbish they get away with.
