I already have the Kennedy half version, which I love, and which compelled me to purchase this larger version for better visibility when in front of a group. This 'Eisenhower' dollar sized version is more visible, but can't be shown as openly and cleanly as the Kennedy half prop. This is because of a visible something that stands out like a freckle at certain times, so to combat it, the cup can't be pointed with the opening towards the spectator(s) or this something will probably be seen. Therefore the seeing the inside of the cup must happen quickly as the cup is being revolved mouth down & up. They still see inside the 'empty' cup but only very briefly, unlike the awesome slow burn display capabilities of the less expensive Kennedy half version. This is a small gripe as the gimmicked coin is outstanding and precision, and the cup is attractive and interacts with the coin perfectly. It's just that one darn thing I wish wasn't.
