I clicked the link thinking "WTF? Didn't Congress do this during the Civil War in an attempt to prevent people from using postage as currency when the CS Dollar began to inflate?

A random bit of trivia - the CSA never issued coins. There were two attempts - a cent and a half dollar - but neither made it past the "proof" stage: https://www.pcgs.com/News/Confederate-States-Of-America-Coin...

Can you give more information? The style doesn't seem even close to the style anyone would write in today - did you think they were like kind of pretending to write in this old-fashioned way, like making fun of old-fashioned writing? did you think it's humor/satire?
