I'd have thought you're looking at the 250-350e range for that one, but it will depend on demand. It's certainly a rare one so list it for sale and don't sell it to pm or lowball offers.
I would recommend you not to sell the shield below 750e or low ballers as max said above imo as the shield is useable in various part of this game and collectors are likely to pay u pretty good for it. Sexy Skin and still many ppl looking for a good dual moded.
