How To Get The Most Renegades Coins

Did you even try the event this time?
The fossils this time give 5, 10 or 20. You know, 5+, just like Dark Link said?

Also: Once you get 1000 points worth of artifacts, you can't pick any more up that day. I've gotten 2 mystical artifacts each time I've tried (5 times so far, 2 chars yesterday, 3 today, all got 2 artifacts) so leave at least 4 days if you want the 64 Renegade coins from this event on a character.

any suggestion where to hunt? i'm having massive issues with this droprate, no artifacts/points at all.
