While your opinion is valid and important - keep dreaming... "if it can be detected" covers a lot of "skill levels." So while that might be a great idea to you, in some coin series, well over 30% of the surviving specimens show "detectible problems" that well over 70% of dealers/collectors CANNOT detect. Be thankful for the TPGS and for the fact that even they don't "detail" every coin that deserves it! BTW, have you ever read the ANA Grading guide? For some straight grades: Luster MAY BE IMPAIRED or the coin may have CONTINUOUS HAIRLINING THROUGHOUT. In both cases these "problems" are easily detected by informed numismatists; yet you may wish to exclude these coins from being graded.
This coin is a reminder of assuming nothing and approaching a slabbed coin with the same jaundiced eye one would with a raw coin.
