Perhaps the real question ought to be, “What should I have done with them?” The Church has a long-standing tradition that every Christian be given a cross to wear around the neck from the time of their baptism. It was also a custom for everyone to own a cross – one that could be placed on a wall over a bed or adorn an icon corner. Then, after a life of praying and bowing down before this cross, it was lovingly placed in the casket and buried in the hands of the deceased as both, a symbol of victory and means of comfort for the family.
Sadly, since very few people seem to possess such crosses anymore, most funeral homes provide them new (at an expense) to grace the departed loved one’s casket during the funeral. Ironically, however, before the casket is closed and taken to the cemetery, many families choose to take these crosses as a type of “keep sake” or memento of the deceased; as if that particular cross was the one which the departed person actually cherished and/or prayed before during life.
Because it is a pious custom that all Orthodox Christians be buried with crosses, icons, and other personal religious items such as their prayer book and Bible, if nothing else is to remain with the deceased in their casket, at least these crosses should.
And as far as your particular situation with multiple crosses, I would either have them buried with you, or divide them up so that they might be buried equally among your siblings.
