I think a few of the Chinese medals I have will not fit even in the 15mm max thickness NGC slab. I sure hope that NGC starts looking into slabs that can fit even thicker medals....they have nothing to lose...they pass the cost onto the buyer for the current fatty slabs anyway....so it's not like they'd have to come up with a new pricing paradigm. I think the Mammoth medal is quite cool looking but my constrained budget has no room at this time for it. And besides, like Stark, there are other terrific Chinese medals already on my "looking to-buy" list. .
