GDJMSP Thanks for the welcome. You are right on those dates and I agree, and I can see what you mean. When I wrote it I did not look at as the three cert were only issued in '83, But all three type were issued sometime it '83, not when they started and stopped. Type 5 is the only one that started and stopped in '83. Type 4 ended in '83 Type 5 started and stopped in '83 and Type 6 started in '83. As for the slab book, I am too late, Condor101 has sold out (I am looking Ebay, search internet but none for sale) and he has not done anoughter printing yet, He is trying to decide if he wants to do the 2nd printing or revise the book and issue a new one. But either way he knows I would like to get one. I will send Condor101 the article for his comments before I put it out, Just to make sure the comments and dates are correct. All of the TPG stuff has really got me inersted in holders. I have been a coin collector for 40 years now. and collected most items but no gold. Thanks Bob
