so I've started getting on the excessive end of my RB points and was wondering what they tend to go for? I haven't found anything so far so if someone could help that would be lovely <3

The sP Smelter gives 10 points for 100K, so somewhere around 10K per point? To be competitive, you might want to ask around 7k or 8K.

Since you can only do one transaction per day, I would definitely sell for higher than smelter prices, not lower.

I would also sell for higher, given that it takes ages to accumulate a large amount of RB points, even with the daily transaction from the smelter.

last few times I've bought rb points from someone else I paid between 3k - 6k per point. depends on who you're buying from, I guess.

I think 20K per point sounds fair. But even for the higher priced items you might sell even higher, due to the fact of what a pain it is to get points.

I noticed that recycle beast current items tend to hit a max of 6.6k so I would probably buy at 5k as it saves a little time but otherwise I could just buy up the items at 6.6k

I think some of the 10K+ valuations are extremely generous.

That would value Ametsuchi at over 300mil, and its not uncommon to find them for 60-120mil.
