Jami` at-Tirmidhi Book 17, Hadith 29
"The Messenger of Allah (ﷺ) cut the hand for a shield worth three Dirham."
That the Prophet (ﷺ) used to cut the hand for a fourth of a Dinar and beyond that.
"I asked Fadalah bin 'Ubaid about hanging the hand around the neck of the thief: 'Is this from the Sunnah?' He said: 'A man came to the Messenger of Allah (ﷺ) with a thief so his hand was cut off, and then he ordered that it be hung around his neck.'"
