Im 17, and i just recently started metal detecting, but also got back into coin collecting. one that i enjoyed was the dimes... i wanted to collect EVERY dme issued, types, not every date. so i went out and found deals on the dimes, and just finished it up today, cost about $35, and have about all the silver to back up the collection as well.. doesnt have to be GREAT condition coins, because of coarse the capped bust is gonna HAVE to be good, perhaps very good condition unless you want to spend hundreds. look on ebay, go to local coin shops.. sometimes they are nicce to us kids just starting out =] have a fun time, and always buy a coin that interests YOU!
