What a cool post, so many questions arise!
How does having a picture of the Queen on the coin effect the silver? Is it a personal dislike of her Majesty, or do you think the people you will sell your silver onto will not buy it because of the picture on it? Can there be other queens on the coin, like Holland?
What's the benefit of government issued silver over non government issued? We know that there is no additional security because we have seen pictures of fake Maples and fake Lunars.
How does having a face value (often way below intrinsic value) make any difference? If you are not going to spend them then what other purpose does having a face value serve? If anything I would think it would be riskier as being legal tender the government might like to lay some claim to it.
Anyway, the only reason I would buy one type over another would be price and availability. The denomination that the coin is in would not really worry me, if the US$ collapses then the ASE is still worth the same amount. I wouldn't pay any extra to have Panda's, for instance, imported into the country over anything available cheaper locally.
I like the Libertads and for a while they were bit higher in price but then the supply increased so they came down a bit.
It is a tough one though, the queen is everywhere
