I won't be able to post any picture for almost two weeks. But SsuperDdave my PCI slab does have a green border and does have a 10 digit identification number. The zeroes are as you descrive (flat sides and rounded tops and bottoms), the 6's rounded body with a straight pig tail proceeding from the 11 o'clock position upward and to the right. At the present time I have no comparision for typesets as my word processing software is open office and does not have either of the typesets that you mention. So based upon your description I'm assuming (you know what that means) that the label is in the Futura typeset.
Thanks for your input, but like I said I will be unable to post a picture for a couple of weeks.
However, I will add that when I purchased the coin from a local dealer I was hesitant to buy the coin because of my unfamiliarity with the grader. The dealer did say that it was an early label, but I marked that down with a jaundiced feeling on my part. So I went with my overall impression of the coin and went with my gut.
