Quite a few years ago I bought a kung fu 1/4 oz gold NYC expo in one of those funny Chinese slabs , I always wondered if it was fake ,but I buried it away and kind of forgot about it ,I ran across it recently and took a hammer to the slab and cracked it out, after close inspection and comparison to some great pictures of an NGC pf70 I came across, I am pretty sure I got screwed , but you know what I'm going to send it in to NGC just as a painful reminder,Stay away from weird slabbed coins! i thought about throwing it up on Ebay before I cracked it out, but I just in my heart of hearts feel its fake and don't want it on my conscience. I have bought some old slabbed Anacs coins that worked out quite well for me STAY AWAY FROM WEIRD SLABS
