Even if they were die cracks, you need a super high power microscope to see them. Keep searching, you’ll find good ones visible with the naked eye.
From the bottom of the C in AMERICA to the closest leaf looks like it is a crack. As stated above, all else looks like flow lines
Thank you all. My photos arent good enough. Its kinda difficult holding my phone to my mycroscope lense to take a photo. The top lense is 10 and the bottom is 40. I cant use the highest magnification because im using a lamp from the side and cant get any light there.
My apologies about the photos and some are 10 x 10 and the cracks run from left to right, between the t and the i, at the top of the s, on the right side, going to the right, and at the top right of the d, and the top of the e.
I have one with the die crack on the right side between the torch and the and the plant. Visible with the naked eye
