What if we told you someone recently paid nearly $15,000 for a handwritten letter? Sounds insane, right? But what if you we told you it was penned by Sir Paul McCartney and addressed to the late, great Prince?

According to Rolling Stone, someone purchased such an item for $14,822 at Boston’s RR Auction. Which is a hefty sum, no doubt, but not too shocking when you consider just how legendary both McCartney and Prince are.

So what did the letter say exactly? Well, McCartney begins with “Dear Princely person,” and then goes on to ask the Purple One for his help in making the Liverpool Institute for Performing Arts a reality. Though it’s undated, it’s likely this letter was written in the early- to mid-‘80s, as McCartney refers to the 1981 Toxeth riots as an event that only took place “a few years ago.” He then writes about his mission to bring a Fame-type institute to his hometown, but would need to secure donations in order to make it happen. He also invites Prince to teach at the school once it was up and running.

The Liverpool Institute for Performing Arts opened its doors about 20 years ago; however, it’s unclear if Prince contributed to its launch.

“We’re not sure if Prince made a donation or not—the vast majority of his contributions were gifted anonymously,” RR Auction Vice President Robert Livingston said in a statement. “It is an incredible letter with personal content relating to McCartney’s philanthropic efforts to extend the gift of music to future generations.”
