prizer

One who places a high value on something.

One who estimates or sets the value of a thing; an appraiser.

But value dwells not in particular will; / It holds his estimate and dignity / As well wherein 'tis precious of itself / As in the prizer.

One who contends for a prize; a prizefighter; a challenger.

Why would you be so fond to overcome / The bonny prizer of the humorous Duke?

Appeareth no man yet to answer the prizer?
