Step 4Enlarge the hole

Enlarge the hole
This is the trickiest part. You need to make the hole large enough to get the dremel tool into it. Once you can get the dremel tool in you make the hole large by grinding away with the dremel, but before you can do that you'll need to enlarge it enough some other way. There are a couple possibilities: you can drill it, use a reamer, or even an industrial hole-punch. Drilling it is a bit tricky because there is not much of the nickel to hold onto while you are drilling - but it is possible if you are slow and careful and don't go too close to the edge with the drill. It may take a few tries to get this done without mangling the coin.

Just reminding people that this ois probably not legal in Australia and the UK as you can't deface things with the Queen's head on them.

No, it's perfectly alright to destroy the Queen's head anywhere(on the coin, not literally) otherwise all the penny token machines would be illegal.

Penny token machines are fake... You insert your penney and it triggers a manufactured one then does what it does to it and your's safely goes into a bin, tough typically i see them for 25 cents now...

... You see the penny roll into the slot, and then you see the hammer flatten the penny, and if you put it in right, you can get the same date on the back.

Well I don't know where you live but it is illegal to deface coins in Australia. As for "penny token machines" I doubt their legality here for that reason. Also we do not have "penny" or 1 cent coins or 2 cents. Defacing our currency can get you in trouble.

Section 16 of the Crimes (Currency) Act 1981 ("the Act") prohibits the deliberate defacing or destroying of Australian coin or banknotes unless consent has been given by either the Reserve Bank or Treasury. As a general rule, such consent is not given on the grounds that banknotes or coin should not be destroyed or defaced. The legislation covers all Australian banknotes, both present and past.

It is also an offence to sell or possess current coins that have been defaced. Defacing a coin includes coating the surface of the money with any sort of material. The penalty for defacing coins , or selling or possessing money that has been defaced, is $5,000 or imprisonment for two years for an individual (or both), and $10,000 for a body corporate. You may also be guilty of the offence of making counterfeit money if you alter a genuine coin.

Where's George is legal because law prohibits writing anywhere on the bill BUT the borders. plus they cant prove that your the person responsible for writing on the border anyways. for all they know it could have been on the bill for weeks.
Dec 7, 2011. 2:14 PM7daytrial says:
Thanks, I know. I was responding to someone that said making jewelry out of money was illegal. I was point out that it is legal and often done. :D
Dec 7, 2011. 5:11 PMsokamiwohali says:

Dec 7, 2011. 6:47 PM7daytrial says:
Ohhhh, Okay! The way I read your comment made it seem like you thought I was saying Where's George is illegal. :D Re-reading my original post I discovered that I didn't really make my stance clear.

DEFACING US CURRENCY IS ILLEGAL
Feb 20, 2011. 10:13 AMfunkytaco says:
Then why can you pay 50 cents to flatten a US penny into a design with popular tourist landmarks? CNN Center right down the street from me does it. Read scottkuma's posts for specifics.
Feb 3, 2011. 6:24 AMscottkuma says:
From the website of the US Mint:

"Section 331 of Title 18 of the United States code provides criminal penalties for anyone who “fraudulently alters, defaces, mutilates impairs, diminishes, falsifies, scales, or lightens any of the coins coined at the Mints of the United States.” This statute means that you may be violating the law if you change the appearance of the coin and fraudulently represent it to be other than the altered coin that it is. As a matter of policy, the U.S. Mint does not promote coloring, plating or altering U.S. coinage: however, there are no sanctions against such activity absent fraudulent intent."

It's NOT illegal unless you try to pass it off as a coin that it isn't. The key here is the word "fraudulently"...

No it's not. It's illegal to alter us currency so that is says it has a higher value or to be used for counterfeiting purposes.
Jan 29, 2011. 9:25 PMslev12397 says:
Yes its ILLEGAL
Feb 22, 2011. 5:23 PMKred14 says:
No it's not. It is only illegal to alter a coin to attempt to pass it off as being of higher value.
An example: the penny pressing machines that are at every tourist attraction. (I think just like that Funky Taco up there. Great name by the way.) Why are they allowed to deface the pennies if it is illegal?
*SARCASM SWITCHED TO: ON MODE* Is it an underground conspiracy controlled by the government? Are they secretly putting little listening devices into the pennies so that they can monitor us? No. In fact, the explanation is that it is perfectly legal.
Another example (i'm on a roll!). Store clerks used to - i don't know if they still do - but they used to use markers to check the authenticity of bills worth $20 or more. Why would they be allowed to do that if defacing the bills was illegal? Because it is legal.
In conclusion, the defacing of currency is permitted only if you are not intending to use the defaced currency for scammery (is that a word?) or skulduggery.

It'd also be really quick and easy if anyone had a small jeweler's saw much safer too!
Dec 13, 2010. 4:08 AMpurplefiona says:
Yep, a piercing saw would be my tool of choice. Drill hole wherever you like, thread saw blade in, cut a nice circle, and smooth off using the dremel. Faster, safer, cleaner. Cool project tho- comment tis merely "my way" of doing it.
Dec 12, 2010. 2:24 PMmista.v says:
If we don't have a dremel, a small file will work, right?
Dec 12, 2010. 12:20 PMGDParduhn3 says:
USE A REVERSING BIT THEY HAVE THEM AT SEARS, WALL MART ETC. .

THEY ARE USED TO REMOVE A BROKEN SCREW OR BOLT FROM A HOLE BY GOING IN REVERSE AND BORING IT OUT, THEY ARE WIDER IN DIAMETER AND SHARP. ALOT FASTER AND EASIER TO WORK WITH. ..
