I want to try casting a copy of a coin in some material like plastic or plaster. Has anyone ever made a 2-sided mold (mould) of a coin? What did you use? I was thinking about silicone caulk, but not sure if it would stick to the coin.

If you have a Hobby Lobby around, you can get a "molding" kit. The product is called Alumilite. You can check on-line also (at the same name) .com. I used their kit for other things with nice results, but it is kind of expensive.
I would be cautious of using anything on a good coin. You may want to try experimenting with a coin that you don't mind possibly ruining. Kind of like the warnings you see on products that say "test in an inconspicuous area first" same principle.

We'd use rubber cement, but that will straight tear a coin up.

Thanks for the suggestions! I'll check out Hobby Lobby. Don't worry, I don't plan to do this to a good coin! I never thought about silly putty! That would work pretty well, actually. CEOcoinshop: The Secret Service wants to eat my chocolate dollars?  |

Yep! I sure have! I wanted a copy of a Roman gold aureus to put in my album to keep at home, because the original coin was stored in a safe deposit box at the bank.
I pressed the original into some aluminium foil, to get two images, one of the obverse and one of the reverse. I had some pure tin left over from the making of a polishing lap used for gem cutting. I poured a small amount of molten tin (has a low melting point) into each mold. On cooling, the images in tin were reduced to about 3/4 mm, then glued together with Araldite. When that had hardened I dipped the copy into gold paint. When that had dried a few days later, the copy went into a 2x2 holder, and the original returned to the bank.
Very obviously a copy, which is exactly what I intended.

I took a Ike dollar cent piece and lubed it with wd-40 whiped it down. Took little wood box filled it with car bondo and pressed the Ike in it made a obverse mold knocked the bondo out of the box after it hardened. It was rubbery but was ok for a mold. I took liquid metal car body filler in a tube poured/smeared it in let it harden it turned grey lightly twisted the mold coin popped out . My dad helped me with all this Had a rough copy of a ike sanded it down onthe outside to round it off spray painted it silver Made around 10 of them for a glued to a belt that went across my chest Then had " the million dollar man " wrestling belt as a kid to were for halloween. When you grow up in the country and poor you have to be creative your you will end up with a white sheet and a ghost costume every year |

Ordinary moulding clay used by kids, and plain epoxy to set on the molded clay. This is good only for one side casting both sides and coming out with a replica coin... well  great to know if one comes out with an easy solution |

I would think it's the US Mint Police. Depending on just how nice a copy you want to make, try just pushing a coin into some Aluminum Foil. Of course this will give you only one side so you would have to do it on both sides. Rub the Foil real tightly and a really nice copy will appear on the Foil. Now pending on what you want to use, you can make some almost copies. If you have some Solder, melt it and pour into the Foil. Or take some 5 minute epoxy, mis with silver paint, pour into the foil. After you make both sides, just glue together. If you use the hot Solder or Lead, make sure you place the Foil on a wooden block. |

Just Carl, The Mint Police, do just that.... Police the Mint. Counterfeit money, coin or bills, are handled by the Secret Service. I have been to classes at Long Beach and other major shows, sponsored by the Secret Service on Counterfeit Detection, and such. I have a coin shop, and according to the law, whenever we buy or receive counterfeit money, we are to "immediately surrender it" to the Secret Service. Edited by CEOcoinshop
