Will it seem kindof shady if I sell giftcards for an amount below what they're worth?

I have many gift cards that are unused and I simply don't want to use, so I thought I could sell them on here just so I can get up to 10 sales and obtain level 2 status. I just put up a $15 iTunes gift card for $10, and although it has 900+ views already, no one is buying it. Do you think its because this looks kind of shady or like a scam? Or should I list it for less?
Thanks
