And give to dust that is a little gilt more laud than gilt o’er-dusted.

From Troilus and Cressida (3.3), somewhat ironically (given his tradition) spoken by Ulysses:

One touch of nature makes the whole world kin,
That all with one consent praise new-born gawds,
Though they are made and moulded of things past,
And give to dust that is a little gilt
More laud than gilt o’er-dusted.

The wordplay requires activating two senses of both gilt (the adjective – thinly covered in gold – and the noun – gold itself) and dust (the noun – worthless matter – and the adjective – lightly covered in such).
