Well I hope this helps... the rares fest before GL on ATL I sold mine for 45mill. Which was a all time high at the time cause usually they go for 25mill from when I remembered. Anyhow, I've seen them as high as 60-75mill on ATL however that is a pretty high high price that will take some patience in selling. So I'd recommend from what I've seen 35-50 perhaps? Hope this helps!
