ubs is good, what's the listing number, I want to bid if you don't. Also, If you, and anyone is worried about fakes on ebay....why doesn't anyone just use a credit card with purchase protection to pay for their purchases. all you have to worry about is if its real once you've received it.
Up to you. They are said to be prestigious bars having come from UBS bank, which is one of the largest prestigious banks in switzerland. In europe it might get premiums, but here no one seems to have heard about it. As far as I'm concerned, gold is gold, I don't care where it came from, as long as price is good. So I would be calculating on spot price. They are refined by Argor Heraeus of Switzerland, and come individually in their own certicards, so price them as you would for pamp. I would prob pay around $65 each. If your looking at same listing as me, remember to factor in the $80 for postage.
Update, their priced at $92 a gram certicard on an australian website. In my opinion, way overpriced, but they also have pamps at reasonable price, so maybe that market value for them.
I have decided to keep away from this one, here is the link, enjoy. http://www.ebay.com.au/itm/280816865643?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2649
I can vouch for the product not the seller. From the pic you can see it is a Kinebar I own 2 x 5gram Kinebars minted by Argor-Heraeus and they are really cool bars. Both of my bars has a rainbow horse and rider on the reverse and the display changes with the angle you hold the bar. You can stack a minted Perth Mint bar and hardly ever look at it, however these bars has a fondle factor that is worth paying a slightly higher premium I certainly wouldn't go out and buy 20 of them as an investment but collecting one and paying an extra $20 premium is worthwhile just for something a little bit unusual in your stack. http://en.wikipedia.org/wiki/Kinebar
