I believe the answer is:
heirloom
But I can't explain it at all! Could you help me understand?
(Other definitions for heirloom that I've seen before include "Treasure handed down in family" , "Valuable family piece" , "Valued possession that's handed down" , "old family piece" , "Cherished item passed down through generations" .)
