No it's the hole that kills collectible value. If the coin is silver it has scrap value
It depends on how good the coin looks... if its all old looking and gross, its not worth as much as it would be if it was cleaner. Also it depends on the date of the coin... older - more $ its worth. the newer - not-so-much $. sorry ;)
Depends on the coin
You could sell them at a coin store, eBay, or bring them to a coin show. And find out what there worth.
Some coins have value to collectors, which can be tremendously more than the face value of the coin. Bear in mind that the condition of the coin is vitally important. Coins are not valuable merely for being old, although being old helps. If a coin is old, rare, and in good condition, then coin collectors will want it.
