If life insurance policy was worth $10,000.00 in 1955 how much will it be in 2009?

Unless the terms of the policy have changed, $10,000.

Disagree.
$ 10,000.00 in 1955 are certainly not $ 10,000.00 in 2009.
There are a lot of things in the middle, starting with inflation.

Anyways, I can’t really answer your question because we do need more details to perform a likely actualization.

I agree with TC Heretic. If you bought a term life $10,000 policy in 1955 it will be worth $10,000 when you die.

Most likely, it’s still worth $10,000, unless you asked for more and paid for it.
