Scholars still baffled as to origin of 2 old Spanish coins found at Glen Canyon NRA

The recent discovery of two ancient Spanish coins near Halls Crossing excited archaeologists at Glen Canyon National Recreation Area, who wondered whether they offered evidence that Spanish explorers, possibly in search of mythical cities of gold, passed through Utah centuries ago.

While the coins were determined to be authentic, National Park Service officials have now concluded that they were not left behind by Spaniards in colonial times. Circumstantial evidence, such as the 400-year difference in the two coins’ ages, indicates they most likely came from a modern collection, but that finding raises other questions.
