Worth its weight in gold 

Something or someone that is of high value.

For instance if someone is worth their weight in gold to you, then in a literal sense (assuming that person is 150 lbs.) their value would be 2,847,000 USD. (Because gold is worth about 1,300 USD per Troy ounce)

The new financial controller I hired cut down our expenses by 26%. He is definitely worth his weight in gold.

What?! 15 bucks for a drink? What, is beer here worth its weight in gold?!
