At what levels are gold no longer rewarded?

I could possibly reach Vykas this week. Would that mean Argos no longer rewards gold next week?

I have found this question asked several times in the past, but it seems it changes when new content is added. Is there a rule that you are allowed 2 raids rewarding gold or could I get Argos, Valtan and Vykas next week?

you lose argos gold at 1475
