Advice on submitting raw proof kilo coins to PCGS for grading
I want to submit raw silver kilo coins to PCGS for grading. Obviously these are huge, heavy, fragile and some are very low mintage modern rarities. Any advice on the best / safest practice to do this? My hunch is to keep them in their kilo coin capsules, and then put the capsule in a heavy duty bubble wrap envelope, and then box them. Would PCGS return the kilo coin capsule after encapsulation? I want to do this right, has anyone else submitted kilo coins for grading here and have some advice. Thanks in advance!
