How much is a 50 euro cent?

Excuse me, could you clarify for me? I'm a bit confused about the value of a 50 euro cent coin. Is it half of a full euro, or am I missing something here? Could you please explain to me exactly how much it's worth in comparison to other currency denominations? I'm just trying to get a better understanding of the value of this particular coin. Thank you in advance for your help.
