It's hard to see for sure but I believe it is. It is also the rarest of the three WAM's so yes it is worth something. Value depends on how bad someone wants it.
Yes - WAM - you can also tell that the FG is close to the base of the memorial. And it does command a good premium - I don't know exactly how much ungraded,
Here is an ungraded one on Ebay - obviously asking way too much as there are NO bids but at least you can compare the pictures to prove yours is a Wide AM! http://www.ebay.com/itm/1999-1C-Wid...105497?hash=item4d469bec59:g:2b4AAOSwgY9XdbOr
