I think this is it

1 = Top left, 2- Top right, 3 = Bottom
1. Canberra 3rd spine above left eye is short
2. Wales, 3rd spine above left eye is longer
3. Canada (Bottom), Echidna is smaller and less detailed

1 and 2 - Lettering is close to edge, 2 has a thick rim
3 Lettering is thinner and slightly further from a thin edge.
Welsh and Canadian coins are roll only pieces. My Welsh coin was from a roll and has a mint fresh appearance.
