After J.Lo seen with $500K Birkin, here’s how many Hermès bags she owns — and the wild total cost estimate

She’s investing in Birkin stocks.

Love don’t cost a thing, but Jennifer Lopez’s Birkin bag collection is worth “several million dollars,” an expert has told The Post, with the many items skyrocketing in value since she purchased them.

J.Lo hit headlines on Tuesday after she stepped out in New York City sporting her Hermès Himalayan Niloticus Birkin bag, estimated to be worth a whopping $500,000.

But that’s only one of the eye-wateringly expensive Birkins that the “Hustlers” star has in her closet, having been pictured — often in sweatpants headed to the gym — with at least 10 of the luxury items over the years.

Michael Tonello, fashion guru and author of “Bringing Home the Birkin”, said Lopez has likely splashed upwards of half a million dollars on Birkin bags, but believes they would be worth way more than that if she ever offloaded them.

“If J.Lo were to decide to sell her bags through a special auction at a major auction house I would guesstimate that you’d be looking at something in the area of several million dollars — minimum,” Tonello told The Post on Wednesday.

It’s no surprise given that Hermès’ Birkin handbags often double in value in as little as five years, and are even called a better investment than gold, according to experts.

Also, the bags are notoriously hard to buy directly from Hermès, and usually appreciate in value over time due to demand.

“Acquiring any of these bags today at an Hermès store is quite complicated,” Tonello explained. “Not one of these bags would be out on the selling floor for you to purchase. These are all ‘back room’ bags, only available at the discretion of the sales associate or store manager.”

Here, a look at some of the super rare Birkins that Lopez owns — and the insane cost of similar bags that are currently on the resale market.

Birkin 25 in Himalayan Niloticus

This is J.Lo’s most expensive Birkin bag because it’s one of the most rare — and therefore coveted — Hermès products on the market.

The crocodile bag features 18K white gold diamond-encrusted hardware and is currently listed on one re-sale site for half a million dollars (excluding tax).

But Lopez is getting good use out of her pricey purchase.

Tuesday’s outing wasn’t the first time Lopez has been seen with this particular bag. She was snapped on a separate outing in New York back in 2020 toting the exorbitantly expensive accessory.

Good bags never go out of style.

J.Lo was first seen sporting this large brown Birkin back in 2008, and she’s continued to get significant wear out of it in the ensuing years.

In 2023, when she was pictured by paparazzi rocking the luxe item with a brown sweatsuit and a pair of Nike dunks while running errands in LA.

The Birkin is also likely to be one of the most expensive in Lopez’s collection, with Cognac Crocodile Birkins in the same 40 cm size re-selling for up to $76,000 online.

Lopez has never been afraid of a bold Birkin — something Tonello says he admires.

“She loves, and is not afraid, of color,” he told The Post. “It also seems that she actually uses the bags in her everyday life, as in they’re not just for walking the red carpet.”

Indeed, the “Love Don’t Cost A Thing” crooner was seen rocking her red Birkin during a shopping spree in London back in 2012, while hand in hand with dancer beau Caspar Smart.

When she was seen out in 2023 with the same red Birkin, Smart was long gone, proving that lovers come and go, but a Birkin is forever.

The re-sale cost of a similar red Hermès handbag: $57,000.

Lopez was seen carrying this mint green Birkin during a romantic trip to Paris with Ben Affleck in July 2022, three months after he proposed.

While it’s unclear whether Affleck gifted the bag to his Birkin-loving beauty as an engagement present, it certainly didn’t come cheap.

While the bag is small, its price tag is anything but.

Sotheby’s is currently selling a similar Birkin for a cool $65,000.

Birkin 30 in Black Crocodile

With its gold hardware, this eye-catching accessory has been a favorite of J.Lo’s for more than half a decade.

The songstress was first seen sporting it during an outing in 2019, and it’s been a trusty accessory for her ever since.

The re-sale price of a similar-sized black croc Birkin comes in at a cool $89,500.

Birkin 40 in Black Leather

While she may relish bags in eye-catching colors, J.Lo is also partial to a plain black Birkin.

The star is frequently seen carrying around the classic handbag while doing business.

In 2018, Lopez lugged the luxe bag to a taping of “Jimmy Kimmel Live,” teaming it with a smart gray dress and classic black heels.

But a classic black Birkin doesn’t come cheap, with one currently listed on a re-sale site for $32,000.

Birkin 35 in Green Leather

No doubt Birkin lovers were green with envy when Lopez debuted this forest-colored bag back in 2020.

Sotheby’s is currently auctioning off a Birkin in the same size and shade, which is expected to fetch around $16,000.

Birkin 35 in White Leather

This classic Birkin was one of the first in Lopez’s collection, with the “Gigli” actress rocking it at a 2012 premiere in Las Vegas.

While it’s the same size as the green Birkin she owns, this white version usually sells for slightly more on the resale market, given that it’s a more classic shade.

Expect to fork out in excess of $17,000 for a similar-looking second-hand item.

Birkin 25 in Grey Leather

In 2020, J.Lo was seen sporting this gray-colored Birkin complete with gold hardware during an appearance at Milan Fashion Week.

Replicating this look won’t come cheap, however, because a similar bag will set you back more than $18,000.

Birkin 25 in Grizzly Gold Veau Doblis Suede

This brown leather suede item is one of the more unusual in Lopez’s extensive collection.

Page Six has previously reported that the same bag regularly sells for about $42,000 on resale sites.

And while it’s unclear when she added the bag to her rotation, it’s seemingly the most recent Birkin she’s purchased.

The “Let’s Get Loud” songstress was first seen showing it last year, and has been pictured with it multiple times since.
