I have seen people listing their cards on localbitcoins.com and even you can sell it on reddit for bitcoins. You can try offering more payment methods to get offers or trade it here on the forum (but some do offer low prices for gift cards).
localbitcoins is only for amazon.com giftcards. reddit i never had an account there, i am going to try, can you explain the procedures?
$1500 woth ebay giftcard some are offering me 750$ that is totally unacceptable. i had amazon balance previous, but i sold it. now i just learnt that ebay giftcards are just for USA purchases.
Mauritius Island seems to be listed nowhere

Ahh! Don't talk about the ridiculous offers one gets for selling their gift cards here. When I was trying to sell my $100 gift card, someone offered $10
I wanted to give it to charity rather than selling at that rate. People also offered 40% face value and I managed to sell it for 95% face value as I offered Payza payment option.
USA gift cards get many buyers on reddit. Even India isn't listed anywhere and I mostly get US gift cards.
Edit: I just checked you want to sell a $1500 gift card. Well in that case, you need to follow few steps on reddit to get your gift card listed
