A Japanese auction site listed SNSD member�Yoona's autographed headband on October 18th, and it's already garnered a ridiculous figure! The auction started off at $139 USD and is now at $1,390 USD with a total of 67 bids (as of the 21st). With only three days remaining, many have been speculating as to how much higher the bids could go. The members of SNSD had already demonstrated their auctioning presence when they participated in Lotte's "Sharing Love" campaign this past April. Yoona's T-shirt sold for $2,239 USD, the highest out of the entire event, while�Sunny's hat sold for $700 and Hyoyeon's T-shirt sold for $451. SNSD is currently preparing for their comeback with their new mini-album, "Hoot". Source + Photos: Sports Chosun
