上衣不与上衣交换，同一的使用价值不与同一的使用价值交换。

《资本论》：

上衣不与上衣交换，同一的使用价值不与同一的使用价值交换。

Coats are not exchanged for coats, one use value is not exchanged for another of the same kind.

原文：

Were these two objects not qualitatively different, not produced respectively by labour of different quality, they could not stand to each other in the relation of commodities.Coats are not exchanged for coats, one use value is not exchanged for another of the same kind.

这二种物品，如果不是性质不同的使用价值，不是性质不同的有用劳动的生产物，便不能当作商品来互相对待。上衣不与上衣交换，同一的使用价值不与同一的使用价值交换。
