U2 has sold well over 100 million record in their career and there are a few super-collectibles among them.
If we go back to 1984, the band issued a translucent 45 RPM 12-inch single for “Pride (In the Name of Love)” in Australia through a subsidiary label of Island Records called Festival. “Pride” takes up all of side one while side B features two versions of a song called “Boomerang” and another entitled “4th of July.”
Only about fifty copies of this 12-inch were pressed. It’s not known how many of these singles still exist today, but when they do come on the market—which isn’t very often—they’ve been known to sell for around $9,000 US.
