You might try the USA 9 setting, it isn't reflected in the manual and may not be present in the Monopoly code either. That change setting is available on my Simpson's Pinball Party, and it is Whitestar, too. It is a straight $1/1 play. Even looking at the Custom settings present in the Monopoly manual, there are no examples showing anything over 50 cents a play and most of the adjustments are to provide more play for less money. You could try some coin multiples using the advice provided by LTG to see if you can cobble something together in Custom. It can be frustrating when you can't set the game up the way you might like for your particular location.

One other consideration, keep the game at 50 cents, turn off replays and match settings. Personally, I don't like that approach but it is something else to think about.

This is incorrect, default factory settings on Monopoly are 1 play 50 cents and 5 plays for $2.00. Unfortunately, there are no optional factory settings for one play over 50 cents, either. Stern increased factory defaults over the years, so yeah today the default setting is 1/$1 and 3/$2, but not back when Monopoly came out.
