If you are a coin collector or a dealer in coins there are bargains to be had on eBay. Just like all auction houses that list vast quantities of coins for sale, the odd bargain has to get through from time to time.
The key is to have patience and to look at all the lisitngs carefully. Target items that have been misdescribed or poorly photographed. Often sellers will send you a clearer image via e-mail which gives you an advantage over other potential buyers. Seek out sellers who have found coins they do not understand and are eager to sell through eBay with poor descriptions. Buy bulk lots, and then break them doen and re-sell them individually.
Hope the above is helpful.
Good luck with your bidding!.
