Hide Minimum Quantity?

Many of our items are one-of-a-kind or made in editions which are sold out and no longer available. We have only one of such items in stock and bevause of their nature it looks a bit odd to have the Minimum quantity field displayed on the detail page. I did set the minimum quantity to 1 in the CSV file for all products sine at this point it applies to all our products. In the future we could have items sold by the box, in which Min qty might be 12, for example. How can Min qty be hidden on those items where it is obviously only 1 (i.e., where it is a unique item), but still display on the other type of item?

Thanks in advance for any insights.
