Most 5 hole USA papers have no dealer stamp and no date.
How can one realistically determine if they were punched by a Rolex ad, or a guy with a punch device?
I have five sets of papers I bought in 1999, that came in a box of other Rolex related crap, from some guy at NAWCC, chapter 1 Philly show that look exactly like the ones punched after the fact.
I guess we will now start examining holes? Hanging Chad? Lol!
Get real, you cannot tell.
Everyone needs to take this in stride and be careful, but to go on a mission, looking to prove anything other than it is impossible to know for sure is an effort in futility and waste of time.
