I doubt whether they were pulled. Only reason to do so would have been if they caused problems for the cameras. Looking at the edge spots of the rest of the rack that is highly unlikely.

I remember he said the quantity delivered with the wrong color was not great, maybe 1000.
I took 100 of them, and no doubt other dealers got some after I told them.

The fact that I didnt see any when I glanced round last time doesnt mean much.
Most LV casinos lose a ton of $1's to souvenir collectors every day. Most could have left the casino anyway.

I figured they were worth a fraction more than the regular ones.
