Consequently, the field’s redemption price is calculated on the basis of fifty sela per beit kor, and if another redeems it instead of the son, it is given to the priests during the Jubilee Year. But if the son consecrated the field and afterward his father died, its halakhic status is like that of a purchased field, whose redemption price is based on its monetary value, and which will return to the ancestral owner, i.e., the son, at the Jubilee; this is the statement of Rabbi Meir. Rabbi Yehuda and Rabbi Shimon say: Even in a case where the son consecrated the field before his father died, its halakhic status is like that of an ancestral field, as it is stated with regard to a purchased field: “And if he will consecrate unto the Lord a field that he has bought, which is not of his ancestral field” (Leviticus 27:22), indicating that this halakha applies only to a field that is not due to become his ancestral field, thereby excluding this field, which at the time of consecration is due to become his ancestral field in the future, when his father dies. The mishna continues: A purchased field that was consecrated is not removed from the possession of the Temple treasury and given to the priests during the Jubilee Year, as the purchase of the land was valid only until the Jubilee, at which point fields return to their ancestral owners, and a person cannot consecrate an item that is not his. The priests and the Levites may always consecrate their ancestral fields and may always redeem their ancestral fields, both before the Jubilee Year and after the Jubilee Year.Mishnah Arakhin 7:5

הַמַּקְדִּישׁ אֶת שָׂדֵהוּ בְּשָׁעָה שֶׁאֵינָהּ יוֹבֵל, אוֹמְרִים לוֹ פְּתַח אַתָּה רִאשׁוֹן, שֶׁהַבְּעָלִים נוֹתְנִים חֹמֶשׁ, וְכָל אָדָם אֵינוֹ נוֹתֵן חֹמֶשׁ. מַעֲשֶׂה בְאֶחָד שֶׁהִקְדִּישׁ אֶת שָׂדֵהוּ מִפְּנֵי רָעָתָהּ, אָמְרוּ לוֹ, פְּתַח אַתָּה רִאשׁוֹן. אָמַר, הֲרֵי הִיא שֶׁלִּי בְאִסָּר. אָמַר רַבִּי יוֹסֵי, לֹא אָמַר זֶה אֶלָּא בְּכַבֵּיצָה, שֶׁהַהֶקְדֵּשׁ נִפְדֶּה בְכֶסֶף וּבְשָׁוֶה כָסֶף. אָמַר לוֹ, הִגִּיעָתְךָ, נִמְצָא מַפְסִיד אִסָּר, וְשָׂדֵהוּ לְפָנָיו: In the case of one who consecrates his ancestral field during a period when the Jubilee Year is not observed, and therefore the field is not redeemed according to a fixed rate of fifty shekels per beit kor but according to its value, when the treasurer announces the sale of the field he says to the owner: You open the bidding first; how much do you offer for its redemption? This method is advantageous for the Temple treasury, as the owner gives an additional payment of one-fifth of the value of the field, and every other person does not give an additional one-fifth payment. There was an incident involving one who consecrated his field due to its inferior quality. The treasurers said to him: You open the bidding first. He said: It is hereby mine for an issar, a small sum. Rabbi Yosei says: That person did not say he would purchase it for an issar; rather, he said he would purchase it for an egg, as consecrated items may be redeemed with money or with the equivalent value of money. The treasurer said to him: The field has come into your possession based on your bid. As a result, he loses an issar and his field remains before him in his possession.Mishnah Arakhin 8:1
