She was eager to make big money quickly; she thought a $65 drop in gold price was a great bargain, which under normal circumstances was; she was an amateur and unlikely had any idea of asset diversification. As Mark Twain said “put all your eggs in one basket, then watch that basket”, Naturally Mark Twain was a terrible investor.

Yes, each gold futures contract represents 1oo troy ounces of gold. Goldberg used all her fund to purchase 100 contracts. Of course, I omitted the commission costs in the fiction for convenience.

Is that one contract can buy 100 oz of gold?
