She [topic-は] already money [object-を] had-received [appearance-様子] was.
受け取る ('to receive, to take in hand') is a compound verb (受ける 'receive' + 取る 'take') that emphasizes the physical or formal act of receiving — taking delivery of money, a package, a document. Compare with the broader もらう ('receive' as a benefactive). The ~ていた gives the resulting state ('was in the state of having received'), and 様子だった layers the evidential 'seemed, appeared' on top. The combination 既に~ていた + 様子だった is the standard kit for narrating an inferred prior event.
