If a casino uses non compliant and non gaming approved chips on gaming tables it could result in a fine up to $10,000.

Since they are non compliant, NV gaming would never have approved them for table use.
Non compliant chips are not sent thru the approval process. Compliant chips must have a denom, such as $5 on both sides or a denom, such as 5 with no "$" and NCV on both sides.

They are either gift shop or giveaway chips.
