You might not have unlocked it yet. IF that's the case then keep your auction going. I noticed you have it for 5 plus days which is a good thing. I put a necklace on here for 5 days and got over 16,000 credits by the end. So I would say keep it running love. As much as I myself would love to have it, you will probably get way more then just 5000 and once you have been on here a while and done several auctions the GIN option will unlock!! good luck!! And I hope it goes for lots and lots of credits.(Which I'm sure it will because of how pretty it is and the fact it's actual silver!)
