With modern minting methods, it is just about impossible to produce a genuine double headed (or tailed) coin.
The only possibility for a genuine coin is that one side looks as you would expect with a raised design, the other side would have the same design indented into the coin in reverse (like you would not expect). This would be because the previous coin had not been ejected from the die before the new blank was inserted. These coins may have some small collector value.
The other possibility is that you have a trick coin sold as a novelty or in magic shops.

Such a coin does not exist. There was no British Penny minted from 1955 to 1960 inclusive.
There were no British Half Pennies minted in 1832 or 1833.
how much is a double died 1957 penny worth
A US "penny" is actually a 1 cent coin, worth 1/100 of a dollar. A British penny (the coin's official name) is worth 1/100 of a pound sterling.
like 300 bucks
Assuming it is a British half penny, it is worth about 25-50 cents in circulated condition and about $5 if uncirculated.
£2-7 (british pound sterling)
