Sahih al-Bukhari Book 86, Hadith 22
A thief's hand was not cut off for stealing something cheaper than a Hajafa or a Turs (two kinds of
shields), each of which was worth a (respectable) price.
The hand of a thief was not cut off during the lifetime of the Prophet (ﷺ) except for stealing something equal to a shield in value.
A similar hadith is narrated from `Aisha through another chain.
A thief's hand was not cut off for stealing something worth less than the price of a shield, whether a Turs or Hajafa (two kinds of shields), each of which was worth a (respectable) price.
