I bought my first two silver pandas today. a 2004 and 2007. Everything looks exactly like it should. One is in a sealed capsule that doesn't look like it would open easily. The other (2007) is in a capsule that has a little divot in the side about the size of a finger nail. I opened that one and weighed it. Only 31.01 grams (478.4 grains). Is this acceptable? It measures 40.05 - 40.1 mm across. From many detailed pictures on the web, all the details look perfect (size of date, denomination, text font and placement, panda bear details). Just wondering. I'm not going to try to open the sealed one. edit: also, on the coin that i removed from the capsule, noticed that the thickness appeared to vary slightly as I rotated the coin looking at the reeding (which is slanted on both coins btw). upon further inspection, i noticed that it looked like a little extra thin silver that was forced to the side of the die as the planchet was struck. should i try to capture this in a picture?
