Whenever I go anywhere, I try to find out if nearby banks have any halves they would like to get rid of. I was gonna walk my dog at the botannical gardens so I called two nearby banks and on the first one.... the lady said she only had 5 loose halves. I asked for the dates and one was a 1964. At a second bank, I picked up $180 in halves and there were two 1964's and one 1966. So, I wound up with about $50 worth of silver for about $5.00 (gas and face value). The little scores add up over time.
If a person learns to take care of their pennies, their dollars will take care of themselves.
