Oh Happy Day

I've just found an entry in the Royal Red Cross Register for Helen Darge, a Staff Nurse with the Territorial Force Nursing Service whose award was dated 3rd June 1916. Presumably she was serving overseas, as she waited nearly four years to have the great honour of receiving her RRC from His Majesty The King at Buckingham Palace on 20th February 1920. However, she lost her precious medal on the very day of the Investiture, and then had to apply for permission to replace it at her own expense. I wonder what happened to the lost one, and if it has a place in anyone's collection today?
