Here is the page on the Silver Striker's website to see these beautiful brass tokens. Many pictures are missing, but you get the idea. Similar to the Nevada $2 Brass token.
Teller House Natural Wonders of the World set includes:
Carlsbad Caverns, Amazon, Giants Causeway, Grand Canyon, Great Barrier Reef, Mount Everest, Victoria Falls
I have a customer looking for them
If you have any to sell or trade, let me know and I will put you in touch with him to make a deal.
Thanks
