I was going through some of my duplicates and I noticed that the two $5 Treasury chips are a bit different. The one on the top row is a different color than the one on the bottom row. The one on the top row also has that "spun" look as does the $1 one right next to it. The one on the bottom row does not have the "spun" look but has a finish similar to the $100 (fake??) next to it. Any help or comments or clarifications would be greatly appreciated. Thanks, Steve B
