Tuesday nights Breaking Vegas was on counterfeiting slot tokens with and EDM
and a big press. First ten minutes have the metal part. It should repeat later in the week. Karl |

I saw it. It was interesting. First thing he learned was that the
form was only part of the problem. He needed to get an exact duplicate of the material as well. If you caught the trailer, they noted that they don't know how many of his "dupes" are still in circulation. The mint that makes the real tokens couldn't even tell which ones were fake for sure. The only way they figured out that someone was counterfeiting tokens was that they were way over inventory on tokens. During the monthly audits to determine how many had been lost or damaged they instead came $24,000 over. Big red flag. JW |

I.e., how he measured/scanned the "real" token to get the digital representation. Maybe the EDM has a built-in scanner, for copying parts. Anybody know? Bob |

I was wondering that as well.

With an EDM you would mold the face of the electrode as a mirror image of
the finished part. EDMers have tricks they use to accomplish this. It could be something like copper plating an existing chip and using that as the electrode, or using a chip to form an investment cast mold, and then cast the electrode. They also use an abrading method, where a part is charged with grit, a special tool applies an orbiting motion and it crush forms the graphite electrode, there is also ultrasonic machining with an abrasive slurry that produces good detail. I once mounted a old copper penny as a cheap test electrode and sank it into a block of aluminum, didn't get great results because the copper eroded too quickly, but then again i'm a noob EDMer.

In article , Karl
Vorwerk says... Tuesday nights Breaking Vegas was on counterfeiting slot tokens with and EDM and a big press. One can fabricate a pretty realistic immitation of a parking lot token with only a turret lathe. Fits the local hospital 'five bucks to part here' machine. So I've been told.

I also heard somewhere that a Belgian 5 Franc piece is the same size as a US quarter, but is only worth about 8 cents. So I've been told. I also have heard that parking meters have little windows where you can see the last two coins put in. Not mentioning this for any reason, nope. |

At one point the CT turnpike issued tokens worth something like fifty cents or so. Turned out that some foreign coin was an exact match and they began turning up in large numbers in the collection buckets. Eventually they realized they were only making enough money to pay for staffing the toll plazas, and maintainting them. So they finally got smart and tore them out, and stopped collecting the tolls. They were only supposed to be "until the highway is paid for" but of course the tolls lingered on for decades after that.

The one I heard was New York, in which you put a subway tolken in a box to pass through the turnstyle. The coin went in, but didn't drop until the rider went through. So the scumballs figgured out that you could run up behind the guy in the turnstyle, and *suck* the coin out of the slot. Yechh ! |

Isn't a Belgian 5 Franc piece worth nothing as they have been using the Euro for several years now? Martin -- martindot herewhybrowat herentlworlddot herecom |
