[PC Heist SC] Pricecheck on Aul

Hello,
Recently I found The Crystal King's Throne (near depth 200, very nice mods too). My friend told me I should try to sell it to people who need it for the Deadly Encounters challenge. Neither him nor I have any idea what the price would be tho. I found nothing on the internet, asking on 820 didn't help either.
If anyone has experience with this kind of offers, please share your knowledge.
Thanks!
