I got these as part of a lot I purchased about a month or two ago and as I was scanning and separating traders something was different about these but I want to see if anyone else can see it.

The first has a smooth coin, light gray inserts and a weak stamp on both sides. Look at the hat - it's not wear.

Both the second & third have dark gray inserts and concentric circles but #2 has a shinier finish than #3. I know there are variations with this chip but no information on the differences between #'s 2 & 3. Should there be?

My scanner doesn't seem to pick up all the detail I'm talking about but there is a difference.

Maybe I'm being to analytical?
