I doubt many of the 5p's will still be out, i think the novelty will have worn off by now and they'll be pretty much in circ. The pennies on the other handhave been round alot longer and many will have been lost, damaged, destroyed, hoarded, thrown down wells... That and i don't tend to see all that many of them. 1971 2p's on the other hand seem far more prevalent, even though they are of a slightly lower mintage.
