any metal workers out there? (im playing with a problem'd coin)

Hyperion

I have a question and I dont know if it's feasible and I want to bounce the idea off someone. I have a nice holed coin. pretty cool thing bought off the bst. there's a hole @ noon.

but, there's also an attempted hole in the temple of the coin 'face'... from the reverse, into the obvserse...
it's looks like a nodule on poor liberties head... (and a corresponding depression on the opposite side of the coin)

my dad (rest his soul) used to have access to a hydraulic press, Im figuring that'd be the thing to push that dimple back through (if you could probably figure out how far to push down on the coin, of course), obviously... there'd be no way to do anyting about the actual detail lost, but at least the nodule wouldn't be protruding anymore. flush with the coin surface would be the ultimate goal ...

Id prefer not to just put some flat metal on the coin and strike it myself with a hammer but I guess that's good too, but I figure a controlled slow push would be better than a strike...

I know this is unusual for a coin board, but where else can I post this question?

If you use a press just be careful not to flatten the whole coin. I have some pretty cool coins that I flattened in a press, and they are definitely flat.

You would need to make sure that the rim height is not higher than Liberty's head height or you will flatten out your rim. But I do not know which of the two methods would produce the best result...

Make sure to take before and after pics.....

I assume there's some way to throw a guide for the press in general.. as I was going to sleep I was mulling over the problem and I think there's no way to guarantee you'll shift the metal as you want...so Im not sure if this is worth the risk.

Using a press from the obverse will flatten the contact surface to some extent... the pressure needed to push the metal will be greater than the hardness of the alloy. Cheers, RickO

You don't need a hydraulic press. A small arbor press would do it and be much more controllable. Here is a link to a cheap one at harbor freight . Most every shop has one more, usually a 2 or 3 ton version. You need to put the coin on a soft piece of wood or other compressible solid so the other side isn't damaged. The business end of these presses is usually scarred and roughened from use so find a piece of copper or other smooth metal to put between the coin and the press. Remember any imperfection on this metal will be imprinted into the coin so get a piece that is perfect. Also the piece shold be larger than the coin so that it's edge doesn't get imprinted.

Operation is by hand so start out easy and inspect after each attempt applying more force to the press until you get the desired flattening.

I don't guarantee good results but you should be able to do as much as possible with this method. --Jerry

here's a method (untested but probable)...,
1)coated the coin reverse in oil after taping the edge.
2)then apply "jb weld" to the reverse and allow proper curing.
3)then remove the coin and remove the "hump" left where the reverse is dented in
4)then the coin should "drop" back in postion
5)then use an arbhor press with an obverse press piece of about the size you need to press back down
mind you you can heat the coin to 300 degrees as jb weld is suitable upto 500 degrees making the coin in a softer state

"i would say don't try this at home" but it sounds like your poking for ideas anyways that you will be trying at home

dumb programmers dont know of the existance of such machines as an arbor press

VERY COOL.

it might be worth it just to have one in the basement, just to say I have one

Sounds like you need Allen Stockton. He can work with coins
like this and make them collectible.

I have owned a Machine Shop for almost 32 years.
Heres what you do:
Sell this on Ebay for what you can get, and buy a similar piece in the condition you want.
You'll find life becomes a lot easier.
As far as Allen Stockton goes, he's good and can do a great repair. Expect to pay $150 to $200 and wait 4 months to get it back.
Is this item worth it?

Just put it in the vise and tighten as tight as you can. Then throw it in the melt silver pile.
