Greetings everyone! I am VERY green/new to coin collecting, so please be gentle

So I have been coming across these types of errors within the last 6-9 months. The first ones were in Angleton, TX, but now I'm getting them in Dallas as well. I took them by a local coin dealer and was basically laughed at, even though he barely glanced at them, while drinking beer with his friends in plain sight...Either way, I was wondering if these are man-made errors or mint errors? I don't have a very good camera on my phone but can take better ones if needed.
Thank you in advance for your help.
Dana
