I have a goodly number of R-10, unique only known - with followed pedigrees - in a small exonumic field.
They would mostly sell in the $400-600 price range. If 10 were suddenly discovered of a single type, the value might drop $100 because there are still more than 10 buyers. It would usually take about 7-10 years for the price to recover to the full previous $400-600.
Although supply and demand does affect prices, in addition to many other factors, the buyer's ability to purchase is at least as important.
In other words, if 10 1804 Draped Bust Dollars suddenly became available, and the prices dropped to $500,000 each, that price would still prohibit the vast majority of collectors from making such a purchase.
Yes, the immediate price would drop, but there are more than 10 buyers who would love such a purchase at half a mil. So what the item is, is greatly influenced by the dollar value, too.
As has already been stated, a $200 value as compared to a $2000 coin would greatly reduce potential buyers.
Specific coins, as has been asked for, is still needed to even give you a general rule.
Essentially, what you are asking is how much is a car worth and how much will the price change with an influx of more of the same car. We don't know the make, model, year, mileage, or condition of the cars you have in mind.
Even general rules are pretty tough without basic specifics.
