Please define "key dates" and give examples thank you.

Key dates are coins that were minted in smaller numbers than their counterparts. Example is 1916 D Mercury dime (264,000 minted) as opposed to 1916 Philly mint (22,180,080 minted) and 1916 S (10,450,000). There are several key and semi key date coins, but basically it means they are more rare than the average coin of that type. Hope this helps

It is the coin (or coins) that most collectors need to complete a certain collection.
