h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

I found this article very helpful, but I'm confused on one point. The author states that Coppers, Tickies and Joeys are 1d, 3d and 4d respectively. However, George Orwell writes (actually it's more implied) in his novel Keep the Aspidistra Flying (the reason I was reading this article in the first place) that a Joey is a threepenny piece (not 4d as the article states):

"He knew the precise sum that was there. Fivepence halfpenny?twopence halfpenny and a Joey. He paused, took out the miserable little threepenny-bit, and looked at it."

Could someone kindly confirm this?
Thanks!

You're quite right. By the time Orwell was writing the 4d piece had long been discontinued and the name transferred to 3d (what I would call a "tickey")When 4d pieces did exist, they were called groats and still appear(ed) in the Maundy Money the queen dishes out to old people every year as the remnants of a very old charity.

Thanks very much! This article, as well as the entire site, is a wealth of interesting information. Keep up the good work!
