Slot Payback Question

At one of the casinos I regularly go to, they have a lot of the older 3 and 5 reel machines that have multiple denominations available. Generally I play the $2-$3 per spin where there are 30 lines at 10 credits per line at 1 cent per credit. They have the option of playing at the 2 cent, 5 cent and 10 cent level as well. There is no progressive, so there isnt an advantage to playing at maximum credits.

The question is this. Assuming I play 20 credits x 10 per line=$2.00 per spin regularly, is there an increased payback percentage if I play 20 credits at 5 per line at 2 cents/ 20 credits at 2 per line at 5 cents / 20 credits at 1 per line at 10 cents. Either way I am playing $2.00 per spin, but am wondering if it is general casino policy to have a higher payback on larger denominations on the same machine or if the machine is programmed for the same payback percentage regardless of denomination.

There is a chance the return goes up if you move up in denom. So playing 10 lines at a $0.01 denom would return less than 5 lines at $0.02. It's probably about a 50/50 chance you move up in denom. On old IGT machines you could tell by the symbols on the screen from the last game changing if the return changed.

Is there a different EPROM chip for each denomination on a slot machine that dictates the hold percentage….ergo 1 cent is a lower return to player (RTP) than 2 cent and so on?

No, there is generally one EPROM or storage media that has all the percentages that the casino chooses from. Old machines may have had one for each percentage but I don't remember those.
