I think we need a new grading scale as it comes to precious metal coins. Since we no longer circulate PM coins, we need a different grading scale.
Since Milk Spots seem to be common, and unavoidable, should we not consider this when grading?
Here is what "I" want in a modern coin.
(2)RELIEF/FIELD condition....no scratches, no contact damage,
(3)Transaction count....how many people held this coins before I did.
Should it pass this test, it is "uncirculated".
General Bullion Grade.
Anything with contact marks (rim dings), anything with multiple transactions -resulting in loss of original luster, irremovable fingerprints.
=== Premium, OR [(current spot)-premium]-ask
Anything with damage obvious to the naked eye. ====spot + small premium
