Re: get Apple coverage to get a new one

Seems you would need to have existing coverage ... you can check online:

If you have the serial number (eg from a receipt for purchase, eMail receipt / records )

Find the serial number of your Apple product - Apple Support

You can enter the serial number to check your coverage:

Check Your Service and Support Coverage - Apple Support

More info: Find information about your warranty or AppleCare plan - Apple Support

All the best :-)
