I see 1981, but that can't be right for a Victorian 'bun' penny ! 
Maybe if I turn my monitor upside down.......... !

Seriously though,
for the 1861 date, Coincraft lists a huge number of varieties, but does not mention anything concerning date numeral variations - apparently, they made quite a few variety hub or master dies.
This coin waaay too worn to be able to identify to which one of those hub or master die varieties that this coin belongs.
Some very detailed study has been done on the huge number of varieties of Victorian Pennys generally, by researchers decades ago, but I guess that you may already be well aware of this.
