You are good, one raven state issue got sold for 2.5 trillion.
As far I can tell this would be the highest Transaktion made for a single ship with infame assets.
Okay edit, the biggest Nummer I’ve found was 2,3 Trillion from a person calming to have sold a RSI (source; Most expensive ship ever sold (v.2) )
Other then that some other dude was asking 2,5t for a RSI : WTS Raven State Issue
