Hi Greg,

[en.wikipedia.org]
The Newark Holy Stones refer to a set of artifacts allegedly discovered by David Wyrick in 1860.
There were other stones found at the Newark site, like the Keystone. Two other stones were also found at Newark shortly after Wyrick’s death (they have since been lost). However, they were quickly dismissed as fakes when the local dentist, John H. Nicol, claimed that he had carved and introduced the stones to the site. Finally, a fifth stone was found at the same site as the Decalogue stone two years later by David M. Johnson, a banker, and Dr. Nathaniel Roe Bradner, a physician. This fifth stone, named the Johnson-Bradner Stone, was also inscribed with post-Exilic Hebrew. The Johnson-Bradner Stone has since been lost.

An inscribed stone reportedly excavated by an employee of the Smithsonian Institution from a burial mound in eastern Tennessee, and published by Cyrus Thomas in his 1894 landmark report, has been promoted by transatlantic contact enthusiasts as incontrovertible proof of Precolumbian Old World contacts. The inscription is fraudulent, having been copied from a Masonic treatise. We present the source of the inscription and discuss other circumstances concerning the stone and its purported discovery.

PURATOIRE RIVER VALLEY - Colorado:
Another significant Hebrew locale is in the Purgatoire River Valley, located due south of La Junta, Colorado, where the oldest written inscriptions in the US are found. (ca.1750 BCE. conservatively), from the earliest Ligature phase of word-formation by ‘tying letters together into a picture’. These have YaH inscriptions identifiable with the Exodus people.
The actual massive rock that appears like a small ship with cleared keel (maybe what attracted his attention to it), of the volcanic basalt from the top Tertiary shelf is a remnant of geological prehistory, which fell two-thirds of the way don the mountain to become what now has stood ground for 2,500 or more years as a massive "Mezuzah" (Bible script found at every Jewish doorway). St at a right angle to the left of the main entry before a natural gateway to this ancient site with Altar having the same writing but exactly the opposite angle Leftward unto facing the River where it is flowing in a strait line perfectly perpendicular to it.
Being the largest of only three ’10 Commandments Stones found anywhere in the world. The others being the “Ogio Decalogue” a much smaller example in a unique type of the post exile Jewish square script and another one of the ”Michigan Artifacts” found written in a Cuneform style of Hebrew graphics!), and therefore most worthy of copy, these are made utilizing the complete Alphabet, the best example of the print closest to that writing of the original tablets, as the Paleo is the only Hebrew having an equal size characters letter set which plotting on both sides of two tablets according to the accounts would have required.

The Gran Vilaya ruins are 400 miles north of Lima and 9,000 feet above sea level in a fog-shrouded region of the Andes that Peruvians call the "jungle's eyebrow." Savoy [1] displayed photos of the tablets, which he said remain in the cave, and sketches of rubbings taken from the stones. He pointed out the similarities between the stylized inscriptions and samples of Phoenician hier-oglyphs.
The hieroglyphs on the tablets are similar to those used in King Solomon's time and include one identical to the symbol that always appeared on the ships he sent to the legendary land of Ophir, which the Bible described as the source of his gold, Savoy said.

So the Los Lunas Decalogue is neither a one of kind nor is it unique in regards to location. Was the 19th century was a time for forgeries of Paleo-Hebrew inscriptions in stone or just labeling them forgeries?

Just food for thought.
