I had to tick other because you missed off tin for a starters. Well the real reason was because i collect quite a few of those, firstly i collect milled silver. Sixpences 1674-1694 (all date/type varities, sixpences 1695-1787 just by date and i get the plumes and roses combinations, but i miss out the provincial mints and the minor varieties. Hammered silver is another area of interest, i'm attempting one coin from every monarch from AEthelwulf to Victoria. (i've just sold all the post Victoria stuff off). Silver pennies are my favourite. Also hammered gold, as part of my monarch collection, if a nice gold one turns up for a monarch i haven't got and i can afford it then so be it. Although i could quite easily collect Edward III Quarter Nobles. Also as a small aside i also collect milled gold in the for of a date set of James II Half guineas. (three to get in total, i need two more... no rush with this though, if i finish it in the next 40 years i'll be content). So to briefly summerise in order of importance. (1 most important) 1) Sixpences 1674-94 2) Hammered Silver or Gold for the monarch type set 3) Sixpences 1695-1787 (just the main london mint varieties, one of each date) 4) James II Half guineas
