I could understand the family keeping them, handing them down- If he was my blood relative I'd never part with one, but perhaps making a casting of them would be an idea- I'd love to have a replica of one, and it would be a popular item for non-musician fans of Rory to wear to remember him?
Just a thought?
Rory playing Western Plain- see the bola tie?
P.S. and it would also help raise revenue for other Rory projects-
as would licensing his music to video software companies such as Rocksmith and Bandfuse

(persistent aren't I?)
