....you thoroughly read all the posts today on the subject !

I am not going to repeat nor digress here, but everyone has the right to the reference book of their choice. The US book is not obsolete until the next one of that issue comes out, which will hopefully be soon, and the TCR is certainly not "gospel", as most every reasonable poster agrees !!

Any given chip can be worth any given value depending on many circumstances at that particular point in time, and any attempt by any book to cover such things is a dart-throw at best !!

Please spend an hour and read all the other posts today and then maybe you will understand ..
