(Note: these are sample pictures of low quality so they can not be used to counterfeit any bills.)
This blue ribbon on the front has three dimensional images that move when you tilt the bill back and forth. It is really neat and would be hard to counterfeit.
The inkwell just to the right of the blue ribbon has a picture of the Liberty Bell imprinted on it. The bell will change color when the bill is tilted back and forth:
On the far right, if you hold the bill to the light, you will see faint image of Ben Franklin. You can see this image from either side of the bill or note or what ever you call them:
There are other security features that are on the older bills that have also been used to secure this new bill. I still say that the look and feel of it reminds me of play money or foreign money. Maybe once they get circulated and folded and crumpled and dirty and just plain used, they will get the old "feel" back. What do you think? Now, you know that you readers are worth a million of those bills to me, so have a great day, you hear?
