Thanks for the heads up. Although I might have handled them a bit during transfer but I would say 70% of the time on the edges, did I mess it up? Right now they're in individual plastic ziplocks until I can find coin sleeves.
Keep them separated from each other so that they don't clang around and leave marks or scratches. .999 fine gold is soft and easily scratched. I'd recommend flips, not capsules.
Would you recommend I have these graded? Also, will NGC prep the coin to retain it's grade in the case once graded?
I would NOT get these coins graded. Lots of risk to you. Leave that risk to your buyer, IMO. Any knowledgeable buyer will be able to tell whether they are genuine, and, if interested, will shell out the cash to get them graded. No need for you to spend $400 to do it.
I'm really curious with the lunar coin since most I've seen online has the RMB value but this one doesn't. And the reverse has dates.
The lunar piece is a medal, not a coin. It does not have a Yuan denomination symbol. I'm interested as well.
