| 1 dollar 1967 - medal orientation |
This kind of minting is called 'medal orientation'.
For a medal to display properly, even if it flips over, when it is tagged to a uniform, the reverse needs to be aligned so that the top of the reverse shares the same position as the top of the obverse. This alignment is called medallic orientation. The opposite situation is seen in some coins, e.g. coins of the United States - but not those of the United Kingdom. In this case, the coin must be flipped about its horizontal axis in order to see the other side the correct way up. In other words, the image on one face of the coin is upside-down relative to the other. For this reason, 'coin orientation' is used in the United States to express the opposite of 'medal orientation'.
Errors and varieties

| 1 dollar 1967 - coin orientation |
Same coin as above, but with different orientation of one of the sides. Very very rare !!!
Coins with coin orientation include United States coinage, South Korean coinage, Thai coinage and pre-Euro French coinage.
Diving Goose 45%
The diving or declining gooze, is a variation of the first coin (medal orientation).Catalogue value rises up to 5 to 10 times the value of the 'normal' coin. Rather rare.

| 1 dollar 1967 - medal orientation and 'diving goose' |
Double Struck
The coin looks terrible, but this has much to do with the fact that it was struck twice.
As we see a goose with two necks.
This error is worth easily 10 to 20 times the value of a regular coin of the same quality. - Very rare.
