Speculate about kant's response to the idea of placing a monetary value on a human life. is doing so ever morally legitimate?

Base on Kant’s response in regards to the idea of placing a monetary value on a human life, in doing this, it is not considered to be legitimate. It is because placing a monetary value on humans is considered to be unacceptable because a person’s value is considered to be something so precious that it can’t be comparable to other living organisms or even other organisms that lies on earth.
