When will repaired scratches be acceptable??

With the advances in precision lasers and 3-D/circuit board printing, when will it be possible to repair scratches on a coin to a degree acceptable to the grading services??

Never, is my opinion.

It will get there and some would say, since the scratch was not meant to be there, taking it off is OK.
only perfect surfaces on a really worn coin. LOL

Any help locating any of these OBW rolls would be gratefully appreciated!
Great transactions with oih82w8, JasonGaming, Moose1913.
There are several techniques accepted by the TPG's today that were not accepted 20 -25 years ago. To name a few:
'Dipping'
Artificial toning
'Chocolatizing' copper proofs that had irregular toning
There is a major pattern coin that had a prominent staple scratch in its proof fields that has since been repaired and is now slabbed.

When the TPG grader can't tell if it's been messed with.

+1 I agree as well.
Is there any reason to believe that it isn't going on right now?
Useless without pics....or are you just winging it?
