I got out to a new park today. Was in a nice residential area. Found my first dollar coin. A Susan B. Anthony. Found a total of $3.78 in clad in two hours. Not very much trash at this park either.
Don't take those SBA dollars light. Check the date if its a 1979 P I think P (see your Red Book) check if its a Near Date Wide Rim type or a Narrow Rim Far Date. The Near Date ones are worth $50.00-$100.00 in a high grade. Check and see if the date is touching the rim if it is then its a Near Date. If it has a space of a few mm or more its not the Near Date Wide Rim type.
