You are powerful pillar collector,although 3 of your Guatemala pillar between VF35-EF40 condition , they are very hard to find,both of them have correct scartches in the Guatemala mint which indicate that they are no doubt genuine! The 1754 pillar has a superior value than later date,but the most beautiful one I like is the 1768 pillar with rainbow toning.
I wanna see more of your collection inculuding portrait pillars!
