Answer 2

Yep there is a extra high leaf and an extra low leaf variety. They seem to be a variety, at least for now, than an error. The mint has not come up with a good explanation for the 2 types yet, at least one that the collectors believe. The price of them is quite high and it will depend on future collectors, as too if the high prices stay that way. I am not an error person, seems we now have people with microscopes looking at coins to find something wrong with them, so they can try and make a fast buck. If they ever come out with portable electron microscopes we will have a flood of new errors. I must admit that it is too bad, most older coins have gone up in prices and a lot of young people can no longer afford them.
