help identifying "coin"

[jnb1994]

So I found this blank coin at work in a roll of quarters. It's the size of a quarter but appears to be completely copper. Both sides are a copperish color as well as the whole rim, which also has a different ridge pattern than a quarter. So I'm thinking its not a blank quarter planchet but I still have no clue what it could be. Any thoughts?

Not sure when the ridges are put into the coin, I'm guessing a quarter before it's been "married" to the other metal ......jmho........HH

It's a metal disc old timers used to call a "slug". It was used to cheat old vending machines. Don't know if they work on newer machines, but worked pretty good on old ones. You can still buy them online, but I don't know what they are really used for .

I don't know what it is, but i've never seen a copper slug with milled edges myself. I mean, back in the day all you needed was a steel washer to use as a slug, worked every time.

I counted the ridges and there were 100 so it's not a quarter. I mentioned the coin in the coin roll hunting thread and someone threw out gold as a far fetched idea. It isn't magnetic. Weighs 6.4g

I think the suggestion about it being a cheater coin is likely it. Somehow it managed to fool current technology. Have you tried feeding it to a coin machine to see if it goes into reject tray? Then again if it sneaks through, you have lost your "unusual coin".

Actually we have an old pinball machine in the basement that we bought from an arcade that closed up. I didn't turn the machine on because it's kind of loud, I don't know how the coin slots work (if they need electricity to work right) but I put the coin in a bunch of times and sometimes it went through and sometimes it went to the reject slot.
