<p>[QUOTE=&quot;Conder101, post: 2301973, member: 66&quot;]Yes I do, and INS was the first grading service.&nbsp; And yes I cover NCI, it began in December of 1984 (Although in their own grading guide, they say they began in 1985.&nbsp; I have certificates dated in 1984.)&nbsp; NCI&#039;s timeline can be confusing though because they used six different generation of certificate but the dates of usage show considerable overlap as if they used whatever certificate happened to be available and made no effort to have a clean transition from one to another.&nbsp; They did not use slabs at first and I have not seen any slab paired with it&#039;s certificate that was dated before late 87/early 88.</p><p><br /></p><p>It is possible you may have better information than I have on INS as all I had was published information to go by.&nbsp; (and I am not infallible)&nbsp; Their announcement that they were now grading coins predated ANACS&#039;s by just a couple weeks, but it is possible they were doing it before they made there announcement.&nbsp; Examination of early INS graded coins would help to clear up the matter but unfortunately they are pretty rare.&nbsp; My earliest example of an INS is not dated but has Charles Hoskins signature so it has to date after 10/76.&nbsp; My earliest DATED INS certificate is from 10/1987.&nbsp; INS was in existence before Hoskins joined them, but I don&#039;t have anything from that period.&nbsp; They also lasted much later than I originally believed.&nbsp; For a long time I though they went out of business in 1992, but I have seen a single example of an INS slab from 1997.&nbsp; I have images of it but could not afford to buy it. (it had a proof 1840 half cent in it.)</p><p><br /></p><p>It is highly unlikely you will find a copy of the book.&nbsp; it is LONG out of print and almost never comes up on the market.&nbsp; the last person I saw who had copies was John Burns and that was maybe five years ago and I believe he has been dead for what two years now and if he still had any they are now disbursed.</p><p><br /></p><p>Thanks for the info about Ken collecting slabs, I&#039;ll have to drop him a line he may have some early ones I haven&#039;t seen and some extra information.</p><p><br /></p><p>And the title of the book was</p><p><br /></p><p>Third Party Grading/Certification Services &amp; Slab/Certificate Varieties[/QUOTE]</p><p><br /></p>
