Is a Coin a Utensil?

It was stated: Rav and Levi have the following dispute. One of them holds that a coin can be used to effect an acquisition of chalifin (the buyer gives the seller something as a token exchange to settle the transaction), and the other one says that a coin cannot be used to effect an acquisition of chalifin.

Rav Pappa explains: A coin cannot be used as chalifin for the seller focuses on the figure which is stamped on the coin, and that figure may eventually become outdated (by the government; it is therefore not regarded as “whole,” and it is different from a “shoe,” which is the torah’s model of a utensil used for chalifin).

Rashi writes that both opinions hold that one does not need to use a utensil in order to effect an acquisition of chalifin (unlike Rav Nachman), for a coin is not a utensil, and nevertheless, they argue if it may be used. And even according to the Amora who holds that it cannot be uses, maintains that way for a different reason altogether.

The Rishonim ask: How can it be that Rav Nachman (who holds that chalifin can only be accomplished with a utensil) disagrees with his predecessors (Rav and Levi)?

Tosfos answers that a coin can be regarded as a utensil, for it may be used as a weight for a scale. Alternatively, it can be used for a necklace for one’s daughter.

The Ritva writes that Rav Nachman does not require an actual utensil; as long as it is something that lasts – similar to a shoe. This would exclude produce. A coin, however, would be included.

The Rashba writes that Rav Nachman is only excluding things that are not similar at all to a shoe.

Tosfos cites an opinion who holds that a coin is a utensil, for it is used for purchasing items.

The Hagaos Mordechai answers that anything which is man-made is regarded as a utensil. This would exclude produce. A coin, however, would be included.
