Wild Purchases People Actually Made With the Amex Black Card

The American Express Business Centurion Card is well known as one of the most expensive and exclusive credit cards in the world. In addition to some excellent travel benefits and access to the top-notch Centurion Concierge service, card members have no pre-set spending limit.

As you might imagine, when you have a credit card used primarily by ultra-high-net-worth individuals and with no spending limit, there have been some massive purchases on American Express Business Centurion Cards through the years. Here are some of the most extreme examples.

Nine-figure artwork purchase

The largest purchase ever made on a American Express Business Centurion Card was reportedly a $170 million painting, bought by Chinese billionaire Liu Yiqian Liu. And the 2015 purchase wasn't the first massive art purchase Liu made with the card. He previously purchased a $36 million antique tea cup from the Ming Dynasty on the card.

Even though the American Express Business Centurion Card only earns one Membership Rewards point per $1 on standard purchases and 1.5 points per $1 for purchases over $5,000, this means that the art purchase alone earned Liu about $2.6 million in redemption value toward travel, or potentially even more value if the points were transferred to some of Amex's partner airlines. And traveling for free for life is exactly what Liu told the New York Times that he and his wife planned to do with his points.

Mansions, jets, and cars

To be sure, most people who spend millions of dollars with their American Express Business Centurion Card don't broadcast it, so there is a definite lack of specific, confirmed reports, although they almost certainly have happened.

For example, one report claimed that the American Express Business Centurion Card was used to purchase a $54 million private jet. Other reports have claimed card members have bought yachts, exotic cars, and even houses with their cards.

American Express hasn't directly confirmed any of these (including the well-documented art purchases discussed earlier), due to privacy concerns. But an Amex spokesperson did confirm to the Guardian that large purchases like these are certainly possible, saying, "It is based on our relationship with that individual card member and these decisions are made on a case-by-case basis, based on our knowledge of their spending patterns."

You don't need the American Express Business Centurion to have no spending limit

While the American Express Business Centurion Card is well known for not having a pre-set spending limit, many people don't realize that several of American Express' card products also don't have one. So, theoretically, you don't need a American Express Business Centurion Card to buy a $2 million Bugatti -- you could make the purchase on any of the following cards:

• The Platinum Card® from American Express -- Apply now for the The Platinum Card® from American Express
• American Express® Gold Card -- Apply now for the American Express® Gold Card
• American Express® Green Card
• Terms apply.

Or, if you're a small business owner, all of these have a business version as well.

However, the key word is pre-set. Just because there is no pre-set spending limit like most cards have doesn't mean that I could walk into a Ferrari dealership with my Amex Platinum card and walk out with a new car. My spending patterns with Amex wouldn't come close to justifying that. But if you're looking for a card that has a flexible spending cap that can let you earn points on large purchases, one of these Amex products could be worth a closer look.
