It was end of 2009-start of 2010. I was 1 month into the game.
Killed serpentis rat and… looted 3 tags. Checked market and it was whooping 450000 ISk each (like 2x or 4x of all my wallet at the time) ! i was amazed and scared! That’s a lot of money!!! How will i move it to market? (for some reason i was always sure i’m always in danger in EvE Online).
A state criminal undocked from a station in an eagle. Somehow he got himself killed by the state police. I went over to the wreck and there were 6 plex certificates (the old kind) inside. They sold for 1 billion each, it made my day.
42 Plex in 2015. A gank target jettisoned it rather than have it destroyed, we scooped it up without knowing the contents… freaked out and had a great day… ah, memories.
ninja looted a dead rorqual, saw a BPC in there (some capital part) that I instantly knew was worth a lot, so I just grabbed that and burned 6 jumps home with it. Got an instasell in corp for 650million ISK.
