The key to success in this hobby is to know what to look for. A trained, naked eye takes a long time to develop for this hobby, but in the long run, if you put time in and study coins, it will be highly beneficial in the future.
Yes, I am 19 years old. I've been in this hobby since I was just 5 years old in 2003. I'm very knowledgeable, and hope to own a coin shop one day.
