The vast majority of coins on ebay are genuine. The more common issue is whether they have been cleaned or are otherwise detail coins that would affect value. But I would be a bit more leery about getting a raw key date or a coin that is commonly counterfeited (like classic gold). The option of getting a quick $5 authenticity opinion from NGC would seem to be the least you should do if you are not an expert and want to go for a high value raw coin.
