Question for coin collectors

I have been collecting coins since I was a kid. My uncle got me into it and I just stayed with it up untill about 3 years ago, just got too expensive and I have not had the time to play with them like I used to. I bought and sold them on eBay and went to a lot of coin shows, also had a lot of people tell me that they had old coins and would like me to see if they had anything that was rare. That could not have been a 1963 Kennedy that went for $100.00 because they did not start making Kennedy halves untill 1964, the 1963 halves are Franklins. The oldest coin I have now is a 1802 large cent in very fine shape. Coin collecting is a great hobby but you have to devote a lot of time and money to it.
