There are already 3 variations listed of the silver Castle Host card from Trump's Castle Casino in Atlantic City, NJ but I just uncovered another variation that was not listed.

The variations have to do with whether or not there is a SM after HOST and different registration marks in the Trump's Castle logo.

1st known variation did NOT have the SM after HOST and had a registration mark after the castle picture in the logo

2nd known variation did have the SM after HOST and a registration mark after the castle picture in the logo

3rd known variation did have the SM after HOST and a registration mark after the word "CASTLE" in the logo

Now the new found variation has the SM after HOST but does not have any registration mark in the logo

Here's a scan of the new found variation:
