The letters N and D could stand for Notre Dame,Our Lady,ie Mary, Jesus’ mother.
Does it close, it looks as if one part might slide over the other ,a little depression might have held something such as a relic,ie a scrap of cloth purporting to be part of Mary’s veil for example.
It was big business in Medieval times .( Pigge’s Bonies, sold as a finger bone of Jesus , Chaucer mentions then in his “ Canterbury Tales about a pilgrimage journey to Canterbury. All the characters etc,if there is no hallmark it is probably lead so handle it with care!
Sacrificial and can be absorbed!
The cross must have been hundreds of feet high! ,,soooo many “genuine “bits sold.
Sooooo many bits brought back from The Holy Land !!!
I think it needs authenticating .
The symbol under the crown, may indicate a regnal number ,King Somebody Richard The Lionheart was Richard The First, and he went on Crusade , in fact he was hardly ever in England but Knights and soldiers would have bought things supposed to be genuine relics, after fighting in The Crusades.
Google the style of crown ,our Riyal Regalia is relatively modern , it might narrow down dates.
Is there a rose on the other side ?
Again some symbolism involved.
How interesting ,thanks for posting.
Viktoria.
Just had a quick Google and the crown is not dissimilar to Richard’s.
