I have a gift card that has no serial number and there is no code under the silver where it said "scratch gently with coin" How do I redeem?

Thanks for posting in the Apple Support Communities Mark_W_Bas,

We understand you're looking for help with a gift card. The following page offers guidance that may help if you're having trouble redeeming it: If you can't redeem your Apple Gift Card or App Store & iTunes Gift Card

If you're unable to read a see a code, you'll want to contact Apple Directly through the link on that page.

Cheers!
