Possibly the most elite of all credit cards.

The
J.P. Morgan Reserve Card®, formerly known as the Palladium Card, is a Visa credit card issued by JPMorgan Chase. This card is in a category of ultra exclusive,
invitation-only credit and charge cards. With its 23-karat gold construction and palladium plating, the card weighs 1 ounce or 28.35 grams, five times the weight of a conventional plastic credit card and twice the weight of the titanium constructed American Express Centurion Card.
The value of the materials used to construct the card is $1,000. It is one of the most exclusive credit cards in the world, and reserved for the most important private clients of JPMorgan Chase.
JPMorgan Chase clients who are invited to carry this card must have a minimum of US$10 million in assets under management with J.P. Morgan Private Bank, and have a median of US$100 million with the bank.
There are only 5,000 Palladium card holders worldwide.
Here’s the thing, despite its exclusivity,
the card itself doesn't offer any special benefits beyond the novelty of being made out of a rare chemical element, palladium.
Thus it is essentially just a status symbol!
