I have been reading lots of info on ancient coins the past couple days. I have read that coins that used to be rare can become more common with I discovery of a bunch of them that we're buried. How often does this happen? Is there a specific coin or era that this has happened to?
I suppose this applies to shipwreck coins as well? Does a large find hurt the value of the coins, or does it create hype?
From what I can tell, hoard coins usually carry a premium and I don't see much (if any) effect on price of the coin types.
Usually the effect is offset by the added interest. With ancients there is no built in market for super rare things unless they are also super interesting. Finding a hoard will enable more people to get interested and add demand. The difference is that no one is trying to get one of every ancient coin so none of you are likely to care that I have a coin you don't as long as you can find things that interest you at least as much as that coin. The exception might be if a hoard of EF coins is found duplicating rarities that were previously only available in corroded condition. Condition is often much more pricey than rarity.
