10C's are not "relatively common," as you'll find out when you list them. (Did you mean "10B's"?) Remember that the available auction records, which smart buyers and sellers both will search before bidding or selling, only goes back a limited amount of time.That means that a machine that is not uncommon, like a 71B, say, can go for a large premium over the average price, as long as there haven't been many sold recently. We have one seller everyone loves to hate who relies on this phenomenon. His may be the only 71B selling at any given time, and he asks a whopping multiplier on a price you might think of as reasonable.
So I guess that means you actually could drive down the prices for 71Bs if you sold five or more all at one time. Your market for these luxury items is not all of eBay, but all bidders willing to buy right now. And what they will be willing to pay mainly depends on recent history, if they are smart, or the phase of the moon if they are not. Of course, for common calcs, like the 10B, it would be hard to affect the price, because the market is much larger. And for true rarities, it would also be hard to sell too many, unless the quantities offered made collectors reassess how many of the items were actually in circulation, and thus to recalculate their worth.
But in the middle, you can get a saturation phenomenon. I bid rashly when I started collecting, but I've gotten cagier. I look for oversupply situations as one way to get relative bargains. Choosing when an auction will close can be important. As a seller, you want to close in the evening in the US, since that's the most active time in the biggest marketplace. People bid at work, too, but things really seem to pick up around 5:30 PM Eastern Time. (As a buyer, you want to avoid those times, if you can.)
