There actually is a 1843 proof half dollar. These were included in the original 10 coin 1843 proof set. There is a rough estimate of 12-15 examples minted with less then this known to collectors today. One famous 1843 proof set was actually presented to or by President Tyler! In the late 1800's, the 3 gold coins from this set were recently sold for 1 million dollars! The other 7 coins were split up after the Pittman auction. I have two 1843 proofs from this original proof set on display on my website...the last multi coin set intact from the original 10!(bar the gold if they are still together) For more info check www.rarecharlottegold.com
