What is a hay penny?

Answer 1

You may be thinking of the term "ha'penny", which is pronounced like "hay penny". It's slang for an old half-penny coin in British currency. Prior to decimalisation, half-pennies were worth 1/480 of a pound sterling. Following the switch to decimal currency new half-pennies were issued that were worth £0.005, or 1/200 of a pound. The half-penny coin was eliminated in 1984 due to its low purchasing power.

Answer 2

There's no coin called a "hay" penny. The name is pronounced the same but it's actually spelled "ha'penny", a contraction of the term "half penny".

Half pennies were used in Britain for about 1000 years so without a specific date it's impossible to provide any kind of value estimate; please post a new, separate question with that information.

Answer 3

Hey, that's a Wheat cent, not hay.

But anyway, 1958 is one of the most common years for wheat cents. In circulated condition its value is at most 2¢.

Answer 4

1 penny
