Some 200 items, including gold rings encrusted with jewels, cufflinks, watches and chains, will go up for auction on Aug 27. Also included is the guitar played by Presley during his famous “comeback” television special of 1968.

Presley’s ex-wife Priscilla worked with Kruse on the collection, although she does not own any of the pieces.

“It brings back memories for sure,” Priscilla told Reuters, adding that it was a running joke with her former husband that he constantly bought or commissioned jewellery for Parker – because the manager already had everything he needed and the Presleys did not know what else to buy him.

Priscilla said she felt protective of the items because she designed some of them, including artefacts with the logo for TCB Band, the musicians who formed the core rhythm section of Presley’s backing band in his later years.

“TCB” stands for “taking care of business”, a favourite expression of Presley’s.

Priscilla said she supported the auction in part because she was weary of seeing so many fake Elvis artefacts for sale. “There is so much product out there that is not authentic at all, and that worries me,” she said.

“I want to know for sure that it is going to go to someone who will care for it, love it.”
