Okay, not really. Today, a friend elsewhere on the Interwebs pulled this exact same April Fool's prank in July. (If you're reading this, I hope you don't mind me stealing it!) He linked to an amazing article about a treasure hunter finding 52,000 Roman coins in Britain and titled the link as if someone had found Nephite coins in Mexico.
The point is that the Romans were in Britain at about the same time the Nephites are alleged to have been in the Americas. Yet while Roman artifacts are constantly unearthed in the UK, we have yet to find any coins, or any other evidence for that matter, of Book of Mormon peoples anywhere.
Frankly, I'm shocked that anyone would assume that we should find any actual archeological evidence of the Nephite and Lamanite civilizations in America, just because we find abundant evidence of ancient Romans everywhere in Britain. Hello...? That was like, totally across the ocean! Think, McFly, think!
Also, Moroni is well-known to have taken Book of Mormon evidence back to heaven in the form of brass plates. Since this is the only action he is known to have taken vis à vis BoM evidence, why would we think he would leave some evidence behind? It doesn't fit with what we know of his character.
Those senines and shiblums and amnor coins were Moroni's wishes, Moroni's dreams. And he took them back. He took them all back.
