Agree with Luke about the Hamilton questions. I read it about current ones. If it meant "has appeared on", it should say "has appeared on", not "appears on". While certainly the latter can be read as all the ones he's ever appeared on, the more natural interpretation to me means those currently being printed.

You can probably get some idea to what extent it was interpreted this way by looking at the size of the answers. I'd say, if we assume people have some idea how American currency works, then 0-1 probably indicates a "present" interpretation, 3 or more will almost always indicate an "ever" interpretation, and 2 is hard to tell from. But that is assuming people have some idea of how American currency works.
