I hadn’t until this morning, and it was definitely interesting to see coins come up in this context. The chain email looks like it has been circulating for a while. It is about the new Presidential Dollar coins. The email claims that the new coin does not include the words “In God We Trust” and goes on to suggest a boycott of the new coin for this reason
Most coin collectors will recognize that this is not correct. The standard mottos “In God We Trust” and “E Pluribus Unum” were included as edge lettering.
This page from Snopes shows the chain email and refutes the claim.
Then again, maybe there is some kernel of truth to the email as some of the Presidential Dollars released into circulation are missing the edge lettering. These errors sell for a premium and are frequently found for sale on eBay.
