Since Occupy Wall Street set up camp in Zucotti Park last fall, privately owned public spaces, or POPS, have gone from planners’ secret sidewalks to every New Yorkers favorite hangout.

The New York World  had the brilliant idea of quantifying just how valuable a few of the city’s POPS are, and it turns out to be tens, and in some cases, hundreds of millions of dollars. Which gives lie to the argument that every time a landlord tries to keep people out, New Yorkers are seriously getting ripped off. Below is a sampling of the POPS and their sticker prices, about which you can find more details on The World‘s site.

• 1633 Broadway: $353 million
• 299 Park Avenue: $167.6 million
• 55 East 52nd Street: $76.1 million
• 455 Madison Avenue: $53.6 million
• 95 Wall Street: $20.7 million
• 1540 Broadway: $0 (the Bertelsman Building never used any of its applicable air rights)
