Chapter 20
Categories of Muktzeh
Laws specifically relating to muktzeh on Yom Tov are explained in Chapter 21.
MUKTZEH MEI-CHAMATH GUFO
37.a. Since a Jew may not wear an article of clothing which contains a combination of wool and linen, such a garment is muktzeh and may not be moved if it belongs to a Jew.
37.b. However, if it belongs to a non-Jew, it is not muktzeh and may be moved.
37.c. Accordingly, if a non-Jew visits a Jew on Shabbath, wearing a coat which contains, or may contain, a combination of wool and linen, the Jew may take his coat from him and hang it on a hook.
38.a. Coins, and tokens which are used in place of coins, are muktzeh.
38.b. 1) Nevertheless, one may move a coin which is attached for ornamental purposes to a necklace or key ring
2) Owing to the fact that it is permanently fixed in position, it is no longer regarded as a coin and ceases to be muktzeh. (See paragraph 44 below)
38.c. 1) The important factor for consideration is whether or not the coin continues to be used as such.
2) Thus, even a coin suspended from a necklace or key ring would remain muktzeh if it were employed for the purpose of removing the sanctity from ma’aser sheni for which an actual coin is essential. (With regard to moving the necklace or key ring see paragraphs 81 and 82 below.)
