This is the first slabbed coin I've ever bought and even though I knew this information is not on the slab I thought I would be able to go to the NGC site and look up an accurate weight and diameter - I don't see that anywhere. Is that correct - once you slab coins you can't access the weight of the coin? How could you ever check for authenticity without breaking it out of the slab (assuming the coin looked smaller or thinner than normal)? I don't have any concerns about this one but no weight or diameter information seems odd. If I can't get the weight this will be coming out of the slab pretty quick. Thanks!
