<p>[QUOTE=&quot;Insider, post: 8327355, member: 24314&quot;]This is easy to answer with some research as I don&#039;t remember the exact dates.&nbsp; Up to 1975-76, before the ANA moved their Authentication Service from DC for CO, the only grades used for internal records at the service were listed in Penny Whimsy plus any modifiers such as &quot;Scratch Damage.&quot;&nbsp; There were no third-party <b>grading </b>services. Only authentication was offered to the public. Note that if you add the expanded #&#039;s that came later (little-by-little: 25, 35, 45, 53, 55, and 58) you&#039;ll see that modern &quot;Detail&quot; grading is virtually an exact adoption of our Technical Grading System <b><font size="5"><span style="color: #ff00ff">**</span></font></b> used to Identify coins for internal records <b><span style="color: #b30000">in the 1970&#039;s</span></b>!&nbsp; <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie8" alt=":D" unselectable="on" unselectable="on" /></p><p><br /></p><p>This system, Technical Grading, was carried over to the first coin<b> grading</b> service at the INS Authentication Bureau (the 2nd AUTHENTICATION&nbsp; service).&nbsp;&nbsp; I don&#039;t have a copy of the first ANA Grading Guide handy; but as soon as that was published, the second TPGS at the ANA in CO included any of the new numbers and adjectives were dropped in favor of numbers. Also NCI came on to the scene for a third opinion if needed.</p><p><br /></p><p>By the time INS was putting coins in plastic slabs (we were late to the party) the MS range of numbers had been expanded.</p><p><br /></p><p>Unfortunately, while all the changes were taking place from 1975 - 1987 I did not think to keep a diary.&nbsp; I only remember the big changes and not when they happened.</p><p><br /></p><p><b><span style="color: rgb(255, 0, 255)"><font size="6">** </font></span></b><font size="3"><span style="color: #000000">Designed by one of our CT members who shall remain unnamed.</span></font></p><p><font size="3"><span style="color: #000000"><br /></span></font></p><p><span style="color: rgb(0, 0, 0)"><font size="4"><br /></font></span></p><p><span style="color: rgb(0, 0, 0)"><font size="4">BIG EDIT:&nbsp; I never saw any INS slabs that did not have the Washington DC address or the next generation with the same appearance except for the PA address.&nbsp; INS moved to PA sometime after 1986.&nbsp; It appears they sold out their name and reputation to outside parties.&nbsp; It appears the &quot;sold out&quot; their name to outside parties.&nbsp; <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie3" alt=":(" unselectable="on" unselectable="on" /> </font></span></p><p><span style="color: rgb(0, 0, 0)"><font size="4">Thanks Burton!</font></span></p><p><span style="color: rgb(0, 0, 0)"><font size="4"><br /></font></span></p><p><span style="color: rgb(0, 0, 0)"><font size="4"></font></span>[/QUOTE]</p><p><br /></p>
