1786 Connecticut Copper Miller 5.7-H.1. Submitted To PCGS

Higher. It's an AU details coin with corrosion. Not an XF details coin with corrosion.

My opinion of course ;)

That would require trust. Trust is to the TPG system as sunlight is to vampires. Make no mistake; the purpose of a slab is not to "protect" a coin. It is a means of fusing a grade "certification" to a coin in a tamper-evident manner. Now it can be marketed as a commodity unit, bought and sold as 1786Connct/MailedBustLeft/XFDetails, instead of a unique thing of beauty. It can be traded in bulk by speculators who don't even feel the need to see the coin itself.
Of course, the slab can be removed by anyone who finds slabs to be a hideous abomination. But that's the real evil beauty of the system; as long as there's no human trust, that TPG grade becomes null and void, with fear of the evaporation of any "resale premium" the system places on it. To get this "certification" back, one must pay again; rejection of the TPG system has now doubled its profit.
