American eagle gold bullion. I am not sure if there is any way to tell which one. %5, $10, $25, and $50 all have the same design as far as I can tell.
I ought to ask for more specifics, but since the early ones obviously don't fit .... @Hommer it is your turn.
This coin (if I should call it that), to me has one of the most beautiful designs. It may be a tough one, but it has been brought up fairly recently for reuse of design.
It is. I may have overstepped the "coin" boundary with this one, but it's design and designer are historically significant to a collector of US Minted coins.
Good. It was slated for use on the reverse of a new palladium coin but hasn't happened yet. I think this reverse is a step above Wienman's walker design and would love to see it used on something like the Washington Quarter.
