Leviticus 27:22-25

27:22 “‘If he consecrates to the Lord a field he has purchased, which is not part of his own landed property, 27:23 the priest will calculate for him the amount of its conversion value until the jubilee year, and he must pay the conversion value on that jubilee day as something that is holy to the Lord. 27:24 In the jubilee year the field will return to the one from whom he bought it, the one to whom it belongs as landed property. 27:25 Every conversion value must be calculated by the standard of the sanctuary shekel; twenty gerahs to the shekel.
