  • Double Headed Coin

    A conversation at work led me to try to make a double headed coin for S&Gs. One of those things where I should've taken pics of the process but didn't.

    Anyhoo, my method was this, make a counter bored brass mandrel that a quarter just fits into for diameter and about half depth.

    Superglue a quarter into the mandrel, head side down.

    Counter bore the tails side off of the coin out to the flange to make a pocket until the nickel just witnesses through the copper core.

    wave a flame over the mandrel so the glue releases and coin can be removed.

    glue another coin on heads down and this time machine to remove the diameter so that it just inserts into the other half, taking some of the material away of the mandrel.

    Face off the tails side until all the nickel is gone and take a thin layer of brass. Again show it a flame to remove the glue.

    Glue the 2 halves together aligning the dates.

    It turned out OK but probably because it is 2 pieces it doesn't ring like a coin when flipped and even feels dud in comparison with a real one when handling it.

    Anybody else made them in the past and have any better methods to share?

    I think it was Mars-Red who posted pictures of a double sided coin a while back.

        is it copper in there? can u solder them together? that would fill in the voids with material that will transfer the pitch..

          Yes, his thread "Magic!" back last December. One I remember well.

            It probably would be better to use a solder paste to join the halves. That would make it more solid. Apply the paste, cook it on 550 degree F for about three minutes in a toaster oven.

            Your machining sequence sounds good to me.

              Thanks for that Rich, his method of making the cover for the penny is pretty much what I did for one half of the quarter (an eighth I guess).

              I'll try again and solder it, good plan.

              S&Gs = ****s & Giggles which is all very well until someone giggles and ****s.

                      Once upon a time, perhaps, when the coins were silver. No longer. Google is your friend.

                          that was interesting how the forum anti swear-er caught my word and star'd it out

                          also interesting what is considered profanity now. On prime time tv they say quite a
                          few that use to be on the George Carlin list. If it can be said on prime time, it should be
                          able to be said on a forum. (humorous curiosity with some logic)

                            Here's one I made earlier

                            Machining sequence as the OP but I bored soft jaws to hold the coins.
                            Halves silver soldered together so it 'rings' when spun.
                            Over here the legislation re. coinage is 'blah blah blah ... with intent to defraud' being the important bit.
                            I waste a lot of time with coins as can be seen here.....
