Why are1898 pennies worth more than 1897 pennies?
They are worth more because less were minted.
When you adjust for inflation which is worth more 1960 pennies 1990 pennies 2006 pennies or 2007 pennies?
Because there are no 1967 pennies. Decimal currency started in 1966. Actually, 1966 pennies should be worth more than 1967 pennies as a 1967 penny would be a fake. Correction This question was posted in US Coins so it refers to US 1-cent pieces by their slang name. It's actually a rather lame joke. The answer is (ba DING!) "1,967 pennies are worth $19.67 which is one cent more than $19.66"
