Leviticus 27:12
11. And if it be any unclean beast, of which they do not offer a sacrifice unto the LORD, then he shall present the beast before the priest:12. And the priest shall value it, whether it be good or bad: as thou valuest it, who art the priest, so shall it be.13. But if he will at all redeem it, then he shall add a fifth part thereof unto thy estimation.
