I found one once in the N in MODERATION. I keep stuff like that but I don't bother putting them in flips. I just put them in tubes with a label like "State 25¢ Rev Die Chips" for example.
The reverses on a lot of the Georgia quarters have sometimes 2 or 3 die cracks if you're into those. They're usually at both ends of the bunting. There are tons of them out there.
Yeah I don't see any cracks on your specimen, but keep looking. There are lots of them. So many so that I've not even been keeping them anymore. Lol
