What is the ruling regarding an item left as a replacement if the original owner knew of the substitution later?

Primary text

If the original owner becomes aware of the substitution, they should take back their original property and return the replacement, treating the replacement item as lost property (luqatah) in essence. If the replacement item remains unclaimed after the year of proclamation, the previous rulings apply. However, if the owner chooses to take the item back or if the judge sells it, the original owner is only entitled to compensation up to the value of their lost property. Any excess value is not due because the original owner never consented to an exchange for the excess amount.
