Copies of David Bowie's chart-topping album Blackstar are selling for more than 10 times their original price, days after his death.
Vinyl versions of the LP, which is number one in the UK album charts, are being sold for more than £400 as fans scramble to get their hands on a copy.
According to the 2016 edition of Record Collector's Rare Record Price Guide, mint copies of Bowie's self-titled debut from 1967 are priced at £800, while top quality copies of 1971's The Man Who Sold The World are fetching around £700.
Record Collector editor Ian McCann said: "If you want to buy Bowie's records, our advice is to wait.
"Massive prices for old albums tend to flatten off and fall once demand subsides. If you are looking for an investment, we would recommend the original first British pressings of David Bowie's classic 70s albums."
As well as splashing out for the music, fans have been paying tribute to the singer by attending concerts around the world.
To mark a week since his death, 900 people crammed into the Union Chapel in Islington, north London, to take part in a marathon four-and-a-half-hour gig.
Established artists such as David McAlmont, The Feeling frontman Dan Gillespie Sells, and The Magic Numbers were among those taking to the stage for the concert.
The event, which overran organisers' original estimation by two hours, was streamed live on YouTube.
The sold-out show - Starman: A celebration of David Bowie - provided an opportunity for people inspired, influenced or touched by his work to pay tribute to the visionary musician, known for hits including Changes, Let's Dance and Ashes To Ashes.
News of Bowie's death at 69, two days after the release of his final album, was confirmed on January 10.
Blackstar rocketed to number one as mourning fans helped the late singer secure a quarter of the spots in the UK Top 40 album chart.
It debuted in first place with almost 150,000 combined sales, making it the fastest selling album of the year so far.
A total of 623,000 Bowie records were sold last week and there were more than 19 million song listens on audio streaming services.
The highest entry after Blackstar among Bowie's 10 top 40 albums was 2014's retrospective Nothing Has Changed - The Very Best Of in fifth, followed by Hunky Dory, The Rise And Fall Of Ziggy Stardust, and Aladdin Sane in 14th, 17th and 23rd places respectively.
