Welder, my number one E-bay rule is to never buy a coin from China. Not even slabbed ones. They make outstanding fake slabs and coins. China includes Hong Kong.
I am also very cautious buying from surrounding countries for similar reasons. Granted mint sets, modern circulated coinage, some commemoratives etc are usually exceptions. But never from China.
Rule number two is never buy from someone who has fakes listed in their feedback. Other feedback comments I will take with a grain of salt depending on what it is.
Buying raw coins worth more than a couple hundred bucks is risky if you do not perform your "due diligence" but I will let folk with more experience talk on that topic.
EDIT: Buying any raw coin without doing research is dangerous.
