In group 2: The last coin is a coin of Queen Elizabeth I, not sure which denomination because I don't know the sizes, but could be a threepence or sixpence? I haven't studied hammered coins enough to really give you a value (plus, in the US hammered coins are -expensive- and so the price will be different than what you can get in the UK). In group 3: The fifth coin is a Victorian farthing, the coin looks to have about fine details if I was grading it, does seem to have corrosion and pitting. Unless it is a rare die variety, it is pretty common and not worth much in that condition. The sixth coin in group 3 is an Edward VII threepence, it isn't in that great of condition nor is it rare, it is only worth silver scrap value. The seventh coin is a 50% silver 1924 shilling and in the condition it is in, is only worth silver scrap value. Sorry I couldn't be much help on the ancients and medieval, but I haven't studied enough of it to be able to easily identify it, though surely someone on this forum can for you.
