Thanks, everyone, for your ideas an encouragement. This is not a serious collection. I started sticking Kennedys in folders that I got in circulation or found while roll hunting, all just for fun. I do admit that I make a trip to the coin shop every year to pick up the current P&D, which sets me back about $1.50, just because I hate to quit something I started. But folders are good enough for this.
I use albums for coins I'm serious about. Besides, for something like this, albums take up too much room.
I'll keep after it.
