Hello, A few years ago I received these Mars Oakley X-Metal Blk Iridium (serial # M023451) sunglasses for a Christmas present. I don't wear sunglasses, so I put them in my bedroom drawer, where they've been ever since. The only thing wrong with them is that the foam they rest in is somewhat deteriorated. Other than that, they're in excellent condition. The only problem I have is that I don't know how much these glasses are worth. I recently seen a pair on Ebay for $589!!!! Are these glasses worth that much??? Any help would be greatly appreciated.
