Hi Mark,
Nice chips!

Your Carson City Nugget looks like a Paulson H&C. If it were a C&J the hats would be more shiny and the inserts would be more sharp in shape.

Here is a comparison of sample chips with LCV H&Cs:

Your carousel inserts look grey. Here is my creme insert. I thought i had a grey one too, but can't find the picture.

Best,
Greg
