Can you now obtain different pickups instead of coins in Greed Mode?

I'm playing some runs in Greed Mode after the last update patch and I've noticed something different in the last one.
Accorging to Rebirth wikia:
At the start of each wave, several pennies are dropped on the ground, which Isaac can use in the shop to purchase items and pickups. The more waves that spawn without pressing the red button, the more money will drop.
But in this run I've obtained a couple of chests, keys and even an item instead of the usual coins.
Here you can see an example, a Stoned Chest and an item (the empty pedestal was an X-Ray Vision) between coins:
Is this a new feature of the last update? Or is there a new item that turns coins in other pickups?
Best Answer
Are you sure that the items/boxes dropped from new waves? On common occasions rocks, mushrooms etc. are destroyed by enemies in the room and those have a chance to drop stuff like chests and so on. I have not gotten anything but coins from the waves. Any item- and chestdrops I got were caused by explosions or any other ways that destroy rocks.
