Conjoined Coins

William and Mary silver farthing 1694


When a numismatist talks about a conjoined coin the reference is usually to one with two or more busts shown facing the same way with one on top of the other. The only British example I can think of is the William and Mary 1688-94. Unless you know otherwise. The reign of William and Mary was brief and their coins are relatively scarce.

Actually, there is one other historic coin, but a commemorative issued last year to celebrate the Queen’s 90th and Prince Philip’s 95th birthdays. The first-ever Guinea struck to mark a double Royal Birthday and the first to feature a conjoined portrait of HM The Queen and HRH Prince Philip since the famous coin shown above.


Detectorist Dave Hobson found something recently that initially had him baffled by the look and feel, and he thought he had uncovered a fake penny.

After weighing and a closer look he realised that what he had was two pennies stuck together. Even then he wasn’t sure so uploaded it to the UKDFD for an expert opinion.

Rod Blunt replied and recorded the find as “Two pennies of Edward I deliberately joined together, possibly by soldering. The exposed obverse is of class 4d. The exposed reverse is of a London coin of class 3. The reason for joining them together in this way is uncertain.”

I asked If anyone knew of a reason or found anything similar to  let me know. Detectorist John Carr contacted me and said that, years ago, he’d found an Edward penny that had been ‘perfectly’ stuck together, one on top of the other.

He’d always thought how curious it was and it had never occurred to him that it might have been done deliberately. He told me that the coins were found on the edge of a beach and it was the very first signal with a C-Scope machine that he was using for the first time. Here’s what he found:

Alan Warner (QM) of the British MDF points out that Philip and Mary had silver sixpences and shillings minted where they were facing each other. They look very combative. I suppose a good name for them would be ARE YOU LOOKING AT ME?coins. Perhaps not. See more at the UKDFD.

From Australia

Ray Swinnerton and John-au of the AMDRH forum have pointed out that there was a ‘conjoined’ 50 cent coin produced in Australia at the time of the wedding of Charles and Diana. Note that they are facing left.

  1. We have nothing like that on this side of the pond, John.. We do get commemoration medallions on occasion; but that is about it.

    I have found coins ‘soldered’ together.. but that was the result of a fire.

    You have the most interesting coins over there..



  2. interesting john mate

  3. Interesting I was expecting to see a double sided coin ie two heads as you would expect of a trick coin!
    Is the weight of the conjoined coins the same as a normal unmolested version, could they have made up the weight by sticking them together to equal a normal coin so when measured on scales in was legal tender?
    an interesting article John as usual

    Very cool John.

    The closest that we have to something like that would be a medal commemorating the first royal visit to Canada in 1939.

  7. Fascinating and great presentation. The Roman emperors who frequently crop up on coins in Wiltshire always seem to be alone, they didn’t miss a trick when it came to self-aggrandising PR.
