If you are referring literally to "half a penny" - that is, to a penny cut in half - then the answer is "little to nothing." If you are referring to a coin whose denomination is a "half penny", then it depends on the country of issue and the condition of the coin in question. The US did not produce a half cent coin in 1880, and neither did Canada. An 1880 Half Penny from Great Britain is valued (according to the Standard Catalog of World Coins) at US$2.50 in Fine condition, US$6.50 in Very Fine condition, US$45.00 in Extremely Fine condition, US$150.00 in Uncirculated condition, and US$400.00 in Proof condition. An 1880 Half Penny from Jamaica is valued at US$2.00 in Fine condition, US$4.00 in Very Fine condition, US$20.00 in Extremely Fine condition, US$55.00 in Uncirculated condition, and US$475.00 in Proof condition.

Coins in average circulated condition are valued at $1.00-$3.00 a real good uncirculated coin could be as much as $30.00
