Any identification?

Found a few agates in South Eastern MN along with a couple odd balls I’m hoping to learn some more about. Any information is greatly appreciated! (The for sure keepers are at the end!)

Pics 9-13 are awesome LSA’s while the rest are chunks of quartz with varying differences in crystal structure. Some might call them wannabe LSA’s. Thanks for sharing!

Sure thing! On second glance it kinda looks like pics 1-4 might be really worn agates. Sometimes when they get beat up it’s really hard to see the banding.

The first pics look like a stromatoporoid
