My Granduncle had decades of unopened gifts in his closet when he died. I think we gave him the only gifts he actually used in the last 20 years- a multi-pocket vest and a broad-brimmed folding hat for his fishing trips.
Right now, his executor/main beneficiary has most of his worldly possessions locked up in a room on the family farm. She can't bear to go through it all...because she's working with the estates of her own father- his brother- and his estate was much the same. Lots of ancient stuff, stored away against a future day.
