(Mishnah): Money of Chulin and money of Ma'aser Sheni that became scattered - whatever he collects is for Ma'aser Sheni until he has completed it; the rest is Chulin.

If they were mixed together and he scooped up a handful, they should be divided according to their original amounts.

This is the rule - if they were scattered, that which he collects is for Ma'aser Sheni; if they were mixed, it is divided according to their original amounts.

A Selah coin of Ma'aser Sheni and a Selah coin of Chulin that became mixed up - he should bring a Selah amount of minted copper coins and say, "Wherever is the Selah of Ma'aser Sheni, it should be redeemed onto this money''. He then selects the better of the two original Selahs and redeems the Kedushah from the copper coins back onto it. This is because they say that in a pressing situation, one may redeem silver onto copper, not permanently, but to then redeem the Kedushah back onto silver.

Beis Shammai say that one should not transfer the Kedushah of his silver Ma'aser Sheni Dinars onto gold Dinars. Beis Hillel permit it.

(R. Akiva): I turned Rabban Gamliel's and R. Yehoshua's silver Dinars into gold Dinars.

(Gemara) (R. Zeira): (The Mishnah taught that if money of Chulin and money of Ma'aser Sheni became scattered - whatever he collects is for Ma'aser Sheni) This is a Rabbinic decree in order to ensure that there is no loss of Ma'aser Sheni money.

(R. Zeira): He must make a stipulation and say, "If the coins that I didn't collect are Ma'aser Sheni, the coins in my hand should receive their Kedushah.''

(R. Yona): That's when he collected some from here and some from there; but if he collected a full row (there is certainly also Chulin in it) and it's the same as if it was mixed and he took a handful (and it must be divided according to the original amounts).

(R. Yosi citing R. Pedaya/ R. Yona citing R. Chizkiyah): The assumption that it completely mixed only applies to wine or oil (but not to solid items such as coins).

(R. Yochanan): Even solid items until the size of olives mix.

Question (our Mishnah - against R. Yochanan): If the coins were mixed together and he scooped a handful, they should be divided according to their original amounts. (Since coins can be larger than olives, why were they considered mixed?)

Answer: It's discussing smaller coins only until the size of olives.

The Mishnah taught that if they were scattered, that which he collects is for Ma'aser Sheni; if they were mixed, they're divided according to their original amounts.

(R. Yosi bei R. Bun citing R. Chuna): The correct understanding of the Mishnah is 'coins that were mixed and scooped up; they're divided according to their original amounts'.

(Tosefta) (Ben Azzai): (The Mishnah taught that if a Selah coin of Ma'aser Sheni and a Selah coin of Chulin became mixed up - he should bring a Selah amount of copper coins and redeem the Kedusha onto them etc.) (Disasgreeing) He should use 2 Selahs amount of copper coins.

(R. Zeira): What's this that I saw in a dream that I will feed Ulla bar Yishmael fatty meat? The next day, R. Zeira came and asked Ulla - why did Ben Azzai require two Selahs?

(Ulla to R. Zeira): By telling the person that he must do this, he will make extra effort to redeem the Kedushah (to avoid losing the use of two Selahs of copper coins).
