I've had a 1979-80 OPC Hockey wax pack for a long time and I'm finally considering having it graded by a TPG (probably PSA)
Never had a wax pack graded before so just a few dumb questions:
1. Does it hurt the grade if gum is broken ?
2. Is the most important consideration corner wear ? Is centering or surface wear as important ?
3. Can one assume that a TPG can determine if a wax pack of this era has been opened and resealed?
Not sure how they determine this but the process must be interesting.

I'm not looking for a grade....just some input.
Thanks and I apologize if I'm in the wrong forum.
