What is the best rate for bulk rares you have seen for pure cash?

Basically, thinking about getting back into Magic, but first forcing myself to clean out my collection. I have easily a few thousand bulk rares, and I kind of want to liquidate them for cash. (I might potentially trade into a deck, but I think I would prefer the money right now.) What is the best cash rate you guys have seen for selling bulk rares?

Thank you in advance for your consideration!
