Estate sale tinnie- real or fake?

[serialins0mniac]

Once again, I am looking for some help on identifying if these are real or not, they are from en estate sale and I am not very good at identifying fakes. I appreciate your time.

I was unsure because this one I have seen online with a hollow back but I had no seen with the back flat like this one.

I saw it too with hollow back.
But the pin look similar to usual.

Another opinions will probably come.
