ציטירנדיקער פּירוש אויף דברים 14:25

ומעשר שני והקדש שלא נפדו – And we don’t need to say that they were not redeemed at all, for this matter is simple, but rather, that they were redeemed, but not redeemed properly , such as the case where a person redeemed the Second Tithe/מעשר שני in broken ware vessels of silver or in a coin that did not have a shape as the All Merciful-One (God) said (Deuteronomy 14:25), “Wrap up the money [and take it with you to the place that the LORD your God has chosen],” in a form that has a shape, and that which was sanctified for the Sanctuary which was redeemed by land and not by money, for the All-Merciful One (God) said (Deuteronomy 14:25), “You may convert them into money” (not the exact quotation in the Hebrew).

ולא מעשר שני והקדש שלא נפדו – such as the case when they were redeemed, but not redeemed according to Halakha, such as when he redeemed the Second tithe out of fragments of vessels/broken ware, which is no longer a vessel or rubbish (see Tractate Shabbat 123a) and not Second Tithe which is redeemed with money that has upon them a shape/form, as it is written (Deuteronomy 14:25): “[You may convert them into money.] Wrap up the money [and take it with you to the place the LORD your God has chosen].” But sanctified things are not redeemed with land, as it is written (Leviticus 27:23): “and he shall pay the assessment as of that day”- a thing that is given from hand to hand.

One may exchange [ produce of] second tithe for uncoined metal, according to Rabbi Dosa. But the Sages say: “One may not so exchange it.” The second tithe may be redeemed with money and brought to Jerusalem. According to Rabbi Dosa one may redeem this second tithe even with a coin that does not have a stamp upon it. According to the Sages it must have a stamp. This is learned from Deuteronomy 14:25, which says “money” in connection with second tithe.
