Why Are Certified Coins Cheaper On Ebay Than The Auction?

It has to do with the heat of the moment and with competition. It happens quite often at an auction that some people just keep on bidding on an items because they have to 'win' and thus beat the other. As if the world will always remember that glorious day and as if all people present at the auction will stand up and applaud as if you've just won the Nobel Peace Prize instead of a coin. With ebay, you as a seller will at least have the security that you'll get a certain amount for a coin: it sometimes happens that no one is interested in a coin at an auction and that it sells for less than prognosed, if even the minimum required bid is made. So it's also a risk for a seller: it may go well, and ideally end up with a few competitors, but it may also become a big disappointment. Plus that, depending on the auction house, the costs for selling may be distributed in a different way via ebay and auctions.

I'm not sure if selling and auctioning can really be compared directly as sales methods. But the above gives an impression of why ebay prices are different (not necessarily cheaper) than auction prices.

There is no legitimate 1794 dollar selling for $10,000 anywhere. If it is selling at $10K, it is a fake.

ebay was my primary place of purchase for raw coins. In general, the BIN prices of most NGC or PCGS on ebay are higher than auction prices realized.

In order of the best results for finding my want list would be: Heritage, Great Collections, Sotheby, shows, ebay

No, it states "hair" not "half"

2 basic factors - "Condition" and "Variety"

I think perhaps he WAS talking about half dollars, but unintentionally.

In the last three months there have been no 1794 Flowing Hair Dollars for sale or sold on ebay for anywhere near as low as $10,000.

However, there are and have been 1794 Flowing Hair HALF Dollars on ebay for under $10,000.

Searching for "1794 Flowing Hair Dollar" returns both Dollars and Half Dollars.
