Who can complete the list of Harrahs, Reno "brass strikes" for me? I have six tokens:

Taj Mahal
Parthenon
Eiffel Tower
Great Wall of China
Roman Colliseum
Egyptian Sphinx

and ???

And whose list is this? It's not the traditional 7 wonders of the ancient world, and doesn't match
any list I can find on the WWW.

I have extras of the first three if anyone needs them.
