<P> Initially it came with an extensive travel insurance all year round no matter how the trip was paid for but since 2012 this insurance is limited to trips which are paid with the card only . (In Australia, the insurance covers all trips, even if paid with another method or frequent flyer miles). </P> <P> The titanium - crafted "Centurion" card was first issued as an upgrade for all plastic U.S. "Centurion" cards in the first half of 2006, with the titanium version being rolled out to certain other countries as well . </P> <P> Some Centurion customers have purchased automobiles using the card or made purchases exceeding € 1 million (US $1.36 million). The card has no preset limit in theory . In practice the authorization is decided upon past payment and spending patterns; the largest purchase ever made on one was US $170 million for Amedeo Modigliani's "Nu couché" painting purchased at a Christie's auction house by Liu Yiqian . It was suggested that the reason for funding the purchase through the credit card was to circumvent Chinese money laws that restrict the transfer of money by citizens out of the country to just $50,000 . </P> <P> The benefits offered to Centurion cardmembers are vast, but they appear to be based on the benefits offered to American Express Platinum cardholders, but with many enhancements . </P>
