Is there a way to see what the sell rate is on an item?

I've been trying to get a stupid forbidden flesh to finish out a build I wanted to do all league and the price keeps jumping away from me. I think I could sell out enough stuff to maybe afford it, but it also seems like someone went in and set a high bar price on it just because and it may not actually be selling at anywhere near that. Trying to avoid dumping 500 div if I don't need to. Is there a way to track actual sales of something like that to see if the price is sustained or not? I watched this happen with a few timeless jewel variants that have already fizzled out.

Unfortunately it's very difficult/impossible to tell the difference between an item being sold and simply being removed from a stash tab. Depending on the specific jewel, 500d sounds plausible - all the useful deadeye ones were going for more than that.
