I sold a 149 for 75mil, but I dont know how much a 146 would be. Hope that's at least a little bit of help though!
Prices are pretty unstable on these. I've bought 149's as high as 60m, but I've also bought several 15Xs (which must have godly chance) for 50m or less. Realistically expect ~30m for this, but you may get lucky and get higher.
