Found a 50c today with a distinct crack right around the edge. It sounds very tinny when dropped. Im fairly sure its split right through so ive been trying to split it into two halves.
Ive tried dropping it and heating and the cooling it very quickly but that hasnt worked.
I there another method that people can think of?
Cold chisel and hammer.:laughingneqw:

Oh no! Piccies first please! :angel: We need to see it before you crack it. :winkextra:
I'd be inclined to leave it as it is. :whistle2:

Me too,maybe one day it will just fall apart.
Is deliberate splitting an excepted thing ?
My best suggestion is soak it in water, pop it in a zip-lock bag and freeze. If it seems to open up then repeat a few times.
Freezing water can crack large boulders.

Put it in water and see if you can get water into the coin. Take it out of the water trying to the keep the water *in* the crack. Put it in the freezer, the water will expand when it turns to ice and might open up the coin a little. Take it out, defrost, fill with water again and repeat until it works or you throw your hands up in disgust.
Addendum to last two (virtually identical) suggestions;
•put a drop of detergent in the water to ensure wetting right into the crack/delamination (whatever it is).

Oooh good answers, I'll await with anticipation.
I remeber getting a few of theses coin, 10 to 15 years ago, but haven't seen one since.
A small screwdriver and hammer works wonders, if you don't mind some damage.
