Or is that just the reflection... IN any case, this is definitely not worth the "perfect premium" its sure to receive.
It's just a modern mass produced bullion coin, why would anyone be silly enough to care exactly how shiny it is?
It toned after being graded. Now, will the seller get a 70 price? Probably not because the toning is unattractive.
The plastic used is semi-permeable to many, many molecules; many od which are less than kind to the coin inside. For this reason, I don't pay extra for "red" copper coins. They are going to tone eventually.
I agree toned in slab as well. Just because its in a slab does not mean it does not need to be stored properly.
