IPod Touch iTunes Gift Card Help?

Sooo.... on my iTunes gift card that i got i was scratching the lable with a quater (i think someone told me it was easyer to do it that way..) and i guess i pressed down too hard or something but it scrached the numbers too, so i can't see the code! Is there a way to get the access code back?? PLZ HELP! It's a 25$ gift card and i don't want to waste it! THX!!:D
