I also love my 2012 Gold "Mini Money" coin set.
It features 8 proof coins, of 11.15mm (0.43 inches) diameter, weighing 0.5 grams each (truly mini money) of 99.99 pure gold.
Each coin features the Ian Rank-Broadley effigy of HM QEII on the obverse, and the design of each of our 8 circulating denominations since decimalisation in 1966 on the reverse (1 cent to $2).
Hard to get a good picture sorry
