Thanks everybody for adding your opinions. As these were what I would consider 'extras' in what I purchased I am not too concerned about what they really are but I would like to make sure they get identified correctly. I can always dream about one of them being a D or Z

Here is a close up of the backs of the ones with grills. Numbers 2, 3, 5, and 6.

I rubbed some pencil graphite on the backs as suggested by Bill Weiss on VSC and it really helps, except for #6.
Not counting #6 (too hard to tell for me) they do seem to have vertical rows. All 3 look like they have 14 rows.
#2 looks to have 16 horizontal rows, #3 may have 17, while #5 seems to have either 16 or 18 depending on what the top and bottom 'rows' are.

And the impression is so perfect, and the stamp is so bad, I'm sure that it's a fake grill.
I think I agree. The grill does look points up and too perfect. And the top and bottom 'rows' don't look like points.
So I think what I have here are a couple of #88s, a fake #94, and a fake #65.
All in favor?
