Disposal of a chalice

In Paul Turner's Blog by Paul Turner

Q:  What is the proper means of disposal of a chalice of a priest who has died? Someone has asked to bury it under the church.  Please advise.  There are no rules for this.

A:  Some chalices go to diocesan archives, some go into the hands of newly ordained priests, others go to parts of the world where metals are expensive and chalices are scarce. I suppose you could bury it, but it could be put to further use.
