...and yet I had a BU '57 calm sea a few months back but it flew out of my Shop like it had wings. I think it lasted less than a day. It went to Canada, where someone obviously collects them! And Rob does, of course. And I do, but then I collect everything. I treasure my halfpennies! But for some reason, maybe genetic, the halfpenny boys don't kick up a quarter of the fuss those farthing boys make. Talk about 'inverse proportion'. Apart from Rob's collection of proofs & patterns, halfpennies are barely ever mentioned on this forum. I often wonder why? Is it the ONE* 'mint flaw' of 1946 you're after, Peck?
