i wondered where you were going with this until i scrolled down.............how i laughed when i did.  i did that. this was his reply...... Books are the seed of world education. It's immaterial the subject. Frankly, the society we are rounded for, it had people for whom literature passed by, and then create a forum where they find likeable souls. Coins as such, bring a major interesting point of looking back, and sometimes they ignore the reason to un-quivalent determination to rise options for their condition (grade). However, nothing have been taken to create a singularity opinion and establish a decisive situation that another soul need to be told how wrong, but leave theirs right. I bring back some received member correspondence to activate that the coin above would be compared with another coin of different date, though and on the book (you disliked!), I quote ..."three coins were struck on dies of same type (above) coining presses at Edinburgh " unquote... with different prices through three grades, and a single with a mark "E". Finally, who had printed prices and choose each grade?. Surely not you, on 18th Century! Regards.
