Another sponsor, Klondike, sold gold & silver coins and had 7500 coins minted to raise money for the team. I've never seen one to hold, although there was one on TradeMe a year or two ago, asking price around $1k if I remember correctly.
Edit: I've just tracked down the old TradeMe listing and it says "This is the rarest of the Klondike series as very few were actually minted."... I'll stop looking down the back of the couch.
