Okla. Stat. tit. 58, § 58-284: Inventory to contain account of monies - Appraisement

unnecessary, when.

The inventory must also contain an account of all monies

belonging to the decedent, which have come to the hands of the

executor or administrator, and if none, the fact must be so stated

in the inventory. If the whole estate consists of money, there need

not be an appraisement, but an inventory must be made and returned

as in other cases.
