I was browsing on HA and somehow I came across this Chinese coin that is slabbed by “GBCA” (Gong Bo Grading) and graded 85 (I’m guessing out of 100?). It’s interesting that it’s almost an exact copy of an NGC slab. Has anyone ever seen or heard of this before? If HA is auctioning their slabs does that mean they have a good reputation? I’ve never seen or heard of GBCA.
