I downvoted, a few of your proof pages had people offering 12 keys for it. That's like 30 ref, so I think the current price is fair.

You haven't shown any evidence of Robros at 10 keys without interest. The lowest price in your list of proofs is an 11 key price. If one of your lis proofs is to be believed, on fellow has a 10 key offer (apparantly hidden, so presumably he found a taker in the meantime).

As it stands, there are plenty of 9 key Robro offers without takers.

With untaken ~11 key requests and untaken ~9 key offers, I'd say ~10 keys is appropriate. But that's not your suggested price. I'd say your suggested 9 key price is no more accurate than the current price.

They will be dropping with the new crate, but let's see how it goes. No votes for now.

These are now found in a common crate.
