Yeah, if they quicksell I'll definitely go 17-19, I just had to weigh them being young against them being two of them, it's like most of the current market :)

They were never quickselling, they were just "discounting" in an attempt to move a vastly overpriced unusual taunt.

As for where those two sellers went, you bought Toads for 14 pure 46 hours after he listed it (based on Sin's screenshot and the time in the compare link)

The only other usable recent public sale is also for 14 pure (and 8 refined, but w/e), and also took over 24 hours:

Roque, the other seller in sin's screenshot, sold his on the 16-17th, six days after it was listed (and it's now in a private backpack, so this took some REAL digging).

The seven keys match. We can presume, obviously, that he got more than 7 keys that were then flipped, but also we know from the screenshot it took the seller almost a week to get 15 (or less) keys.

From that private history we also get:

Sold for Planets Batters (~13)

and:

Sold for Vivid Nano (way outdated at 22, struggling to sell at 20, realistically is highend support)

There's also this, arrangement:

That comes to 13 keys, but that's obviously too bulky to be used at evidence.

TL;DR

I think the low end here is fine here despite the buyers. Roque in particular has proven it so impossible to get more than 15 in pure, which would make a range of 17-19 woefully inaccurate. There's LOTS of evidence at and around 14, it's not necessarily quickselling (the remaining buyers at that price have tens of thousands of buy orders up and reserve the right to refuse any purchase, I doubt they're valid buyers), and it's very definitely the common trading point. I intend to "keep this thingy up," yes.
