Ooo, travelling for chip labels, that sounds fun
The more I think about it, the more I like this idea for a set of labels. It's a classic theme, pretty much everyone is at least familiar with the seven wonders, plus it's different.
I guess modification possibilites would be some kind of small border on the edge, maybe with some text (perhaps the name of the wonder?). And of course, a denomination could be marked on the label somewhere.
