Robert,
1, Create Art work
2. Take art to gaming for approval.
3, make chips.
4 notch a sample and take it to gaming.
5. Gaming matches it to art and approves it for delivery to casino.
Gaming should match chip to previously submitted art work. ( Art would have been approved before chips were made,)
Do they catch everything? No.

Robert P has sent me some information on these chips. Will digest it and get back to you.

Porn stars, Hmmmmmmmmmmmmmm. That one has been beat to death. <g>
