A gold, gemstone and diamond lion's head pendant led a sale of Elvis Presley memorabilia at Graceland on August 14, achieving $82,500.
The lot was specially designed for the singer and was worn by him on a number of occasions, including his meeting with President Nixon in 1970.
Elvis had sent a rambling letter to Nixon earlier in the year asking to be made a Federal agent.
He wrote: "The drug culture, the hippie elements, the SDS [the radical organisation Students for a Democratic Society], Black Panthers, etc. do not [underlined] consider me as their enemy or as they call it "the establishment".
"I call it American and I love it."
The bemused president (who recognised a good PR opportunity) invited him to the White House, officially made him an honorary agent and presented him with a DEA badge.
The two also discussed working on an anti-drugs album to be called High on Life, which fortunately never materialised.
A 1977 Cadillac Seville, the car Elvis drove the day he died, sold for $81,250.
It was later given to his fiance Ginger Alden by his father Vernon.
We have this incredible signed photograph of Elvis taken during his army years.
