How important is it to get coin increasing perks early in a run?

I had one T1 run where I reached wave 6053 and had 71M coins-per-hour with a total of 807M coins. A future run (after I had even upgraded my modules a bit) ended at wave 7134 with a coins-per-hour of 56M and a total of 822M coins.

I'm pretty sure my card loadout was basically the same (at least had the coin increasing cards and nothing like deathray on), so I can't figure out how I had such a different coin gain other than I think I got all the coin perks later on in the run the second run than the first one.

Is there anything obvious I might be missing? I can give more info as needed (as far as I remember anyway).
