Gifting and exchange
Tolkien indicated that gifting and exchange are important in parts of Middle-earth. In the Shire, the Hobbits have "mathoms" (Old English: māþum, treasure, gift), objects passed from hand to hand as valued or sometimes unvalued gifts. Many were stored in the museum or Mathom-house at Michel Delving.
