(ok this is my first CoinTalk post) Hello, I love coin hunting, mostly been looking threw penny rolls (mostly for the pre-1982 copper) but recently I shifted into nickels because there is more copper in the nickles than the penny plus theirs also nickle in them. I also am look for rare dates *found a 1970S small date once* while I look threw the rolls plus anything that contains silver. But back to my question which should I spend most money on? pennies, nickles, dimes, quarters, halves rolls? Thanks! P.S. if you may try to say why I should go with for example "dime rolls instead pennys".
