A few tiny nicks which can be seen on these rather merciless pictures, but would not be seen with the naked eye, prevent the second coin being graded as absolutely perfect.

Curious dimple on Elizabeth's neck (2nd pair). I would not have a clue what caused this.

I have seen rainbow toned American silver, but NOT Australian silver.

Why is that?

Maybe the differences in composition, their coins being 90% and ours 92.5% or 50%. Maybe the planchets get treated a little differently? I've got no idea. Some of the morgans that develop into 'monsters' are stunning to say the least.

A few reasons:

- An overwhelming majority of uncirculated Australian pre-decimal coins are either fresh roll pulls (usually brilliant white) or have been cleaned so statistically it's already unlikely to find them.

- I believe that rainbow toning is caused by sulfur in envelopes they're stored in which wasn't a common means of coin storage in Australia. You seem to get rainbow toned Australian coins out of UK though so maybe they used such envelopes.

- Americans like rainbow toning so there's incentive for them to artificially cause it.
