pidyon hekdesh = kinyan kesef
I never thought about it in that way before, but the halacha of pidyon from hekdesh is not simply a din in issur v’heter, to remove the status of kedusha from an object by paying hekdesh, but is a dinei mamonos halacha of kinyanei kesef. The gemara (Kiddushin 29a) writes that if a person did a kinyan meshicha from hekdesh but did not yet pay for the object, the person must pay the increased price if the object appreicates in the interim. Even though meshicha removed the object from the reshus of hekdesh, the kinyan is not complete until payment is made (this proof is brought by R’ Moshe Soloveitchik).
