The 1874H penny above is a standard Freeman 71, namely 7+G by his die pairings.
However, your 1861 halfpenny is much more interesting - it is a Freeman 282, coincidentally also a 7+G pairing by his halfpenny die pairs, BUT the 1 over 1 to the left was only recorded by Iain Dracott back in 2004 in his series of halfpenny articles in Coin News magazine, and not many are yet known. As halfpennies tend to be less focused on by collectors, I bet there are a few more around and unnoticed, but once again you have nailed a pretty rare, if not especially (yet) sought after, variety! Well done again!
