Striations and Proof Grading
This is a general question for anyone but mainly those who have had some grading experience at the TPGs (I think there are a few on these forums anyways). In Rick Tomaska's book on 1950-70s cameo proofs, he mentions striations and how they would be pre strike (deep) hairlines on the planchet, that when the coin was struck, would not be fully removed. They can be distinguished from hairlines by how they generally run under the devices, whereas hairlines would not. My question is that since striations are technically a mint made defect, do they count against a proof's grade or do the TPGs not take the time to distinguish the two? (I wouldn't blame them). My experience is rather limited in this field as proofs are notoriously hard to grade form pictures, and forget about distinguishing striations from hairlines. Thanks!
