It is as it came in-I never opened the Glassine Envelope and just assumed that is a bad poor (I've seen a couple like that)-but (as I just got a scale in yesterday) I will weigh it later(4 am here) and get back to you.
I do not know about "Shaving" ,seems like too much work for so little profit ,but you were correct. The actual weight is .9 grams Having worked as a dye caster many years ago-- I tend to believe the edge being like that is more likely from a dye stick rather than a shave(hate to think that a mint I buy from often has gone dishonest)--Nice catch-Thanks
