Just pulled 3 2013 2 pence from my pocket change - looking to pick one to keep[ One is normal, the other two have approx 120 degree die rotation, ie with obverse normal at 12 o'clock, the reverses are about 8 o'clock A sample of 2 out of 3 not a good statistical sample as they could well all have come out the same mint bag does this happen often these days?
