It might command a premium being new, but I wouldn't want to pay extra for it, if buying it to hold onto. In that case I'd want it for the same price as other gold.
I suppose you could pay a bit more now, if buying it to re-sell quickly, since you'd probably get it back.
I'm not certain how these are trading.
I am not going for this ebay deal, can't see why Microsoft needs to give away a couple of hundred.
Maybe bullion is excluded ?
