Between $100-200. And If it's those +red iridiums, it could go higher depending on condition. I got lucky. The one I got recently was sold as just a 0.4, and was on auction. I saw the photos and took a chance the post was mislabeled. That's how I got my 0.4 squared. Was under $200.Username Hidden said:Free bump but also wondering what is the going rate for a pair of those 0.4 squared?
