I went to Subway today–St. Patrick’s Day–for lunch. I ordered my lunch paid for it only to discover that they gave me a 1964 Liberty quarter as part of my change. Our pre-1965 coins were made of 90% silver and when I checked its value on the web it turns out that it was worth $6.50 or just slightly more than the cost of my lunch. Luck of the Irish!
