Alexander Zweig, a business visionary, collector, and angel investor — also the son of the late Wall Street investor Martin Zweig — has secured a buyer for his $9 million Tribeca loft, according to exclusive information provided to Gimme Shelter.

The all-cash deal is slated to close on Wednesday. “It [found a buyer] in a day,” a source said of the 62 Beach St. aerie.

The home’s stylish aesthetic was inspired by the nearby Greenwich Hotel.

Measuring over 3,350 square feet, this two-bedroom, 2½-bathroom residence is a combination of two units situated on the sixth floor. The space has notably showcased Zweig’s remarkable memorabilia collection.

The collection features items such as Charlie Sheen’s helmet from “Platoon,” Clint Eastwood’s gun from “Dirty Harry,” and Arnold Schwarzenegger’s shotgun from “Terminator 2: Judgment Day.”

There’s also John Belushi’s driver’s license, which is in one of the apartment’s powder rooms, and memorabilia from the film “Edward Scissorhands.”

The collection, which also includes sports memorabilia, art and photography including a black-and-white Kate Moss photo by Mario Testino — along with vintage typewriters, rare books and more — was not part of the sale, sources said.

Zweig first purchased 6B in 2012 for $2.89 million, followed by 6C in 2013 for $3 million.

A six-year renovation to combine the units followed.

“It’s a really unique space and has some of the most insane pop-culture memorabilia inside — it’s like a museum,” said Ryan Serhant of Netflix’s “Owning Manhattan,” who shared the listing with Greg Vladi, also of Serhant. 

Zweig inherited the collecting gene from his late father Martin, an investor who once predicted the 1987 stock market crash.

The elder Zweig paid a then-record $21.5 million for the Pierre Hotel’s penthouse in 1999. It was on the market for $125 million when he passed away in 2013, leaving his collection — including Marilyn Monroe’s “Happy Birthday, Mr. President” dress — to Alexander, his brother Zachary and his second wife Barbara. 

The Beach Street abode opens to a foyer with custom closets and a modern chandelier that leads to a great room with red-brick walls, exposed brick and tin ceilings.

There’s also an open living/dining area with a built-in wet bar and a chef’s kitchen. 

Design details include three exposures, a pocket door that opens to a windowed home office with built-in storage, and 20 windows facing south and west for sunsets over the Hudson River.

The main bedroom comes with cove lighting, a walk-through closet and an ensuite spa-like bath. Both the bedroom and office open to a courtyard-facing balcony. 

The residence is in a former coffee, tea and spice warehouse, the Fischer Mills Building, which dates to 1860 and is now a full-service condo.

The renovation was led by DHD Architecture & Interior Design’s Jill Diamant, an architect, and Emilee Pearson, a designer.
