800k is what i would have stalled it for, and would have successfully sold it

It's the market rate, anywhere ranging from 500k - 1mil. Depending on the number of similar items in the marketplace at the same time, but then of course there are many players which will all reach L20 and also sos is still considered rare drop, of course not so much as som or sosun. So Congrats, u sold it for a good price!
