It's not Fool's Gold, Copper Pyrites or more commonly Iron Pyrites. It could be Jet or Basaltic Glass. Pieces of minerals collected off the beach are notoriously difficult to identify as they are no longer in context with their original bedrock. The mineral you have could be local - unlikely as most of Norfolk and Suffolk is Cretaceous in nature - but is more likely to have been carried down from the North during the last Ice Age.
The last link I have provided demonstrates how to identify different minerals. Have fun.

E-mail a picture to a geologist at Stony Brook University. I'm a geology student there and, being that you found it in Suffolk county, someone in my department may be able to help you. I would recomend Prof. Hanson from the list below.

If it's glassy, then it's probably obsidian, i.e. volcanic glass.
If it's not glassy, i.e. just a black stone, then it may be shale.
