Shaper Item

Found this in BSC, using it on my miner. Only found like 3-4 similar ones in Standard, priced anywhere from 5ex to several mirrors. BSC seems to have none yet - at least not for sale.
Any realistic price checks for this? I'm not necessarily interested in actually selling (yet), more just curious how much I could/should get out of it in case I want to roll another build.
