ABC 34 Defaced Die quarter with a left-facing obverse bust obscured by lines and a left-facing horse and rider on the reverse with triskeles below. This type was struck somewhere in the French/Belgian border region in the 2nd century BC by an unknown tribe and possibly dates to around 175 BC plus or minus a couple of decades either way. Used to be very rare, I listed 17 examples in my 2003 book but there are perhaps 30 or so known.
