Shouldn't one say 'Old and Gold' instead of 'Old but Gold'?

I REFER to this week's Views from the Top (BT, May 10). While some good ideas were shared across the two pages most of the comments were repeated cliches of the nature of "eloquently saying nothing".

I applaud Prudential for putting their money where their mouth is, and wonder what the other companies are actually doing, beneath the veneer of caring.

The reference to mindset is interesting, and I think it showed in the headline of the piece, "Old but Gold". Why is old the other side of the spectrum of gold? Could it not be "Old and Gold", as we would say, "antique and valuable"?
