Yes, but they're not always subject to the complete - and individual - coverage of flat album pages during their storage life. Some are partially covered, leading to the "crescent" toning we see on Morgans. Some are completely covered, and tone from the outside in like coins from an album. Either way, the overwhelming majority of them receive their sulfur from the atmosphere around them, rather than direct contact with the physical source of that sulfur.
Very interesting. This supports some of my writing in the past about how the PCI green-label coins were accurately graded.
Wow.. That coin is WAAAYYYYYY overgraded. I wouldn't pay $1.00 for it. But I will give you $0.99 for it. LOL Man that is a gorgeous dime. I bet those colors actually pop pretty good with the luster, but just are not showing up so well in these images. Nice grab Paddy, I'm jealous for sure. I would have given it a 66 FB.
This is not one of the old PCI slabs. It was made not that long back in order to fool people. The font is different.
Actually I'm wrong in a way. PCI has had several owners over the years. There was one owner that started using the 10 digit serial numbers again to fool folks. This is not one of them but it's not one of the old slabs.
I was at a show and a dealer showed me one of his recent pickups. It was an 1892 O in an orange PCI holder graded MS-65. The coin was a solid MS-64 at least. The dealer had bought the coin in the slab from another dealer for $80. The original dealer had distrusted the slab and felt the coin was worthless inside it. The knowledgeable dealer priced it accordingly.
This is exactly why I buy the coin and not the slab. A lot of great coins can be bought at bargain prices because a dealer won't trust the holder.
Learn that; the real "sleeper" slabs are the ones with that Futura-family typeface using perfectly round letters and slab-sided zeros. The coin here - I looked at it in-hand at Gettysburg shortly after Paddy bought it - is quite deserving of the grade and FB designation. The toughest part of the bands on this example is the center band on the left, and in the last image he posted yesterday, that spot is where the highlight on the image is the brightest. Even almost washed out, the band separation is clear. It was nicely bought.
