Got some coins from my dad,I found out what two of them are well I hope I got it right.
Could anyone confirm that the first two are:
an 1804 George III 3rd Guinea (2.8grams, 17mm)


Second
George III (4.2Grams,21mm) Half Guinea.


I used
http://www.coins-of-the-uk.co.uk to identify the first two don't have a clue about this third one though.
It's from 1788 it weighs 4.0grams and is 25mm.


If the pics are not clear enough I should be able to take better ones later :).
Thanks
-Gareth.
