'Estimation' in the Bible

"If anyone commits a trespass, and sins unwittingly, in the holy things of Yahweh; then he shall bring his trespass offering to Yahweh, a ram without blemish from the flock, according to your estimation in silver by shekels, after the shekel of the sanctuary, for a trespass offering.

He shall bring a ram without blemish from of the flock, according to your estimation, for a trespass offering, to the priest; and the priest shall make atonement for him concerning the thing in which he sinned and didn't know it, and he will be forgiven.

He shall bring his trespass offering to Yahweh, a ram without blemish from the flock, according to your estimation, for a trespass offering, to the priest.
