Credit Card Change ?

It depends a lot on what you mean by your credit card "changed".

If it was a renewal or the card was replaced by the issuer for any reason, then you're likely ok. Your card was pre-authorized or verified when the order was taken; the issuer will honour that authorization on your old cc number and charge it to your account. Generally, it will show up on your statement under the old card number. Their systems are pretty well designed and this is a common situation.

However, if you cancelled one card, and this is a new card, then of course you'll need to contact the mint with the new card information - just updating your profile is not enough to retroactively change prior transactions.

As Rockdaddy said, it's worth a call to your cc issuer and the mint to ensure you have no issues.

Definitely call them. While receiving to my 20 for 20 coin subscription, my credit card number changed. I just called the RCM and updated their records.

I called them and told that I have new card. They changed it for all the outstanding orders.
