What is the ruling on the dower if the object is lost and is fungible or non-fungible after the contract?

Primary text

If the object is lost and is fungible (from objects of like kind), the husband claims half of its equivalent kind. If it is not fungible, he claims half its value at the lowest point it was from the time of the contract until either the time of taking possession or the time of enabling him to take possession, depending on established scholarly disagreement. This differentiation is made because if the object appreciated, the increase belongs solely to her. If it depreciated before he took possession, the loss falls under his guarantee.
