For me it's 1 & 3, then 2 then 4. I do try to avoid holed coins (although I've got a couple that have been neatly plugged). I'll accept chipped coins if a full round coin would be very difficult to get /expensive.
If you collect, say, pennies. and have a spare £1000 or so, would you rather have (A) an 1860 (copper) in Fine, or (B) an 1831 (currency) in BU? I'm firmly for (A), but suspect I'm in the minority, (My valuations might be a bit out as I haven't collected 1d's for many yers).
