The first coin is a British (Ceylon) 1856 1/2 farthing (https://en.numista.com/catalogue/pieces8480.html) that I think is the "Krittania" error coin, although it does say "Krittaniar", not "Krittania". The second is an 1844 for comparison.
Does anyone know anything about this coin? I can't find a value, and google yields nothing.....
