Thanks, trig. I won a 20 coin lot for $20 that had a bunch of nice Canadian coins, including a proof penny, 3 nickels, dime, and quarter from 1967, 3 other nickels including a 1951, a 1907 dime, and some goodies from other countries.
Cyprus 3 Mils 1955. After 1 hour, any Cyprus 1955 coin. After 2 hours, any coin with a flying fish or one from Cyprus. After 3 hours, any coin with a fish.
Here is the total mintage by decade for Lincoln Wheat Cents: 1909 - 1919 2125708369 1920 - 1929 1664218000 1930 - 1939 2214331000 1940 - 1949 10566921670 1950 - 1958 9245977454 More than three times as many were minted in the 1940s + 1950s (19.8 billion) than the previous three decades combined (6.00 billion). Add in attrition over time and it's expected that you would find more from these later decades.
