Interesting video on coin grading. I still wonder how they determine the difference beween a PR69 and PR70. Most of the modern proofs look so perfect that I would grade a lot of them 70.... must be something they are looking for that knocks them down to a 69. Or maybe it has to do with how much sleep they got the night before!
One thing I noticed in the video was that the graders were not wearing cotton gloves when handling the coins. Seems to me they should be especially when handling high value BU Gold coins. I thought that would be standard practice at a place like PCGS.

I too was caught wondering why this was knowingly filmed and still not a glove to be seen in any part of the grading process.......

G'day, note for Ultvikefan: it is important to note that that method was completely impartial as the grader was blindfolded from start to finish.
Anyway, that technique has been superceded by the "smoke and mirrors" method. By simultaneously applying BOTH the smoke AND the mirrors, all possibility of error is eliminated.

People who have been handling coins for many years typically do not wear gloves of any kind as it reduces tactile sensation. However, people who are less experienced at handling coins should probably wear them to avoid any misplaced finger prints. The only time I wear gloves is when I am inserting a coin into an album and have to touch the face of the coin to seat it properly.

I still think that a grading company should also wear gloves, while Bio's explaination has good reasoning," reduces tactile sensation", I like that. The people who seal the coin also do not wear them seems, well, not a good Idea. In my opinion a grading company, should take all the needed or protective pre-cautionary measures to assure TOP quality "Handling"...Great clip, Thanks, Arjmuat...

that is why you can get a coin graded and it show no finger prints and after a year or so a finger print will appear, or you send in a coin with no prints and get one back encapsulated with a fat thumb print on it (have actually had this happen before and was highly upset)
