The CGC sent them an email stating that it would take a bit longer because they need to "scientifically authenticate the manufacture date of the paper used" because the issue the shop sent in to CGC had perfectly white pages still, so they were weary of it being a fake or just an original cover stapled around reproduced pages....which wasnt the case, it came back graded 100% legit 6.0....The majority though you are right, its just people who have been grading and collecting comics for 30+ years and really know their shit, but if it comes down to them needing to authenticate the age of an issue, they will do so by having a paper specialist come in. What Im getting at is CGC and PSA will bring in the proper people to accurately date an item if their hired graders can not come to a conclusion on it.
