On a Ryzen 7 1700x I've done Aeon which was mining about 0.25/day and Raven(RVN) is about 20/day cpu mining currently

There is a thread that was started here https://bitcointalk.org/index.php?topic=2683343.80 but has seemed to go off topic

Also worth watching if you have the time is newly released coins as the difficulty is generally low and they can be cpu mined for awhile easily. But also they could be a worthless coin. Personally I try to do several across my machines that are 6+ cores and see what they can mine in 24 hours to get an idea.
