Hi,
Noone has answered you. I have a link which lists famous relics by country. They are spread throughout the world.
Here in Sydney at an Opus Dei centre they have a piece of bone from an Apostle. They have no paperwork proving it’s authenticity, but the small piece of skin on it has not decayed in over 20 yrs and it’s not preserved or anything.
The following website is good on this subject. But I have not checked out the whole site.
