50 Euros Daniel O'Connell

Daniel O'Connell secured Catholic Emancipation in 1829 after decades of agitation, forcing Westminster to pass the Roman Catholic Relief Act despite fierce opposition from George IV, who reportedly wept with rage at being compelled to give royal assent. Ireland has issued commemorative gold in his name before, but the five-nines purity here — finer than the standard .9999 used by most sovereign mints — is a deliberate production choice that places this issue among the purest struck by any European central bank.
