are these 1887/6 O morgan dollar overdate error

I was wondering if anyone could tell me whether if any of these are the 1887/6 O overdate?
These are the best photos I could take.

Not my area, but with an overdate, you can usually see the number underneath that was minted over it.
Have to take your word on the O mint mark on the reverses.

 

First, welcome to the neighborhood @Frankieyy !

Have you checked them against the VAMWorld site?
