David Bowie — The Prettiest Star (1973)
If you have the picture-sleeved copy of the 45 RPM single, you should know that you have something rare in your hands. It is one of the most iconic images in the history of rock and roll! Apparently, avid Bowie performed this song over the phone while he asked Angela Barnett to marry him. Marc Bolan, who is his main rival for the title “The King of Glam” also plays the guitar on the track. Things turned sour between them when Bolan’s wife told Bowie, “Marc is too good for you, to be playing on this record!” Clearly, Ziggy Stardust had the last laugh. A conservative estimate for the record is $2,000.
ABBA — Hova’s Vittne (1981)
The special promotional copy of this ABBA single was exclusively distributed to record companies. They only printed 200 copies of this red vinyl. The side A features “Hova’s Vittne”, while side B has “Tivedshambo”. The Swedish band is one of the most commercially successful bands ever. Their lineup consisted of two couples: Lyngstad and Andersson, and Fältskog and Ulvaeus. Unfortunately, neither marriages withstood the test of time and fame. If you have Hova’s Vittne, you can sell it for $3,500!
