If your pulse has not returned to its morning resting rate one hour later, you are still having an allergic reaction to the food you ate previously and cannot get a decent result on another food until either your pulse slows again or until the next morning.
CoinTrackers.com has estimated the 1964 Lincoln Penny value at an average of 1 cent, one in certified mint state (MS+) could be worth $12. (see details)...
Value: $20 - $50. This penny has a double-printed obverse (heads side) that makes the LIBERTY and IN GOD WE TRUST look blurry. The error has happened before, in 1969 and 1972, and those versions of the coins are much more valuable.
