You can get the info you're requesting by using the ChipGuide Query Facility, which can be found in the Search menu.

1. If you just want to see chips, set the Collectible Type to "Chips - All"
2. Set the Date Range to "Equal"
3. Enter your desired year in the Date1 box.

The example below shows the location of these three settings, with the year set to "2021."

An optional part of this, if you want to see a list of the casinos rather than pictures of the chips, is to set the View to "Text." See example below.

You can further refine this by selecting Region, State, and City, for example "United States", "Nevada", "Las Vegas."
