One in the same. I've read that if you ask a Chinese seller to Omit the words, copy, replica, reproduction, etc,
stamped on collectible coins that are pouring out of China, They are happy to do so.
I've also read that EBAY has been flooded with fake coins, some valuable and some not valuable.
I've also read that some of these coins are encased in PCGS and NGC "Slabs" that are produced in China.
As far as categories, They are literally everywhere.
