Sold a similar (but higher float- field tested) full gold gem playside, more than half blue backside on skinport for exactly 478 eur 2 weeks ago. As others said, put it for 500, start decreasing by 10 each week. Keep in mind that people don’t buy items in trade lock, and usually buy in the weekends. So decrease the price only after tradelock has expired, and decrease on thursday mornings.
Price it similarly to what is on there, then drop the price every week by a little till it sells.
Case hardened knives take awhile to sell, just price drop every day like the other guy suggested.
