Why are some options priced so differently from very similar contracts?

I'm learning options and am not a large investor but hoping someone can share some knowledge.

I'm specifically looking at MSOS $10 strike for 3/24.

This has been between about .08-.10 for days while other strikes expiring in the same day are vastly different

Example; $9.50 strike for 3/24 is .71
10.50 strike for 3/24 is .74

But then the 10 strike is just waaaaay lower. It's popped up to about. 34 a few times although I've never succeeded in actually selling at that price but what gives? Why is it priced nothing like the others that are so similar?
