Advice please

Hi guys,


I recently acquired an ex-brooch of one of these: https://en.numista.com/catalogue/pieces39626.html. I would like to remove the remnants of the brooch, but not sure if this is a good idea to try it myself? Can someone advise please!

I would say a steady handed person with a dremel would easy get the main off then you're talking filing it back, probably want to file the same way too keep it uniform I would say some very very fine wet n black then you'll need to polish the surface flat. It's never going to look great, just better. I would say this is probably a lot easier to do with copper/brass coins because the solder would just melt with propane.

Would it be possible to heat the added on portions with a soldering iron and use a wick to suck the solder out?

I would heat the parts to be removed and pull them off with a pair of pliers

 Yes, this is my best advice, because this tragedy was done with solder, so I would leave any solder that did not come off with the pin parts.

Gets my goat when I see a nice coin made into a pendant in that fashion. Best way is to make a ring that surrounds the whole thing so it free-floats.  It least it's not a hole drilled into it.

What Glorkar said...Get a good soldering iron and remove the post.  Have some fresh desoldering braid and remove the left-over solder.  That is if it's regular solder.  Silver solder may be a different story(?) Never worked with that material.  I'm an electronics tech, not a smithy.

Here's a wiki on desoldering...

If you have a buddy into electronics he may have everything and the experience with desoldering that he may be able to preserve the lettering.  It couldn't get much worse.

I'd do it for you but you'd have to mail to Switzerland.  You're in the UK so post not too bad.  Just throwing it out there, not expecting a bite.

Post some picts when you get it fixed. =) Good luck!

I would just use a blow torch, avoid heating the coin as this will discolour it. That's why I suggested using pliers to pull it off as quickly as possible.  If it's done properly it will be silver solder and will be a bit of a pain.

At least it hasn't got a hole or two drilled in it which is my particular pet hate.

I saw a USSR Palladium 1991 25 Roubles made into a pendant and it broke my heart.  
An example can be found here. Way to go, ruining a rare and perfectly beautiful coin.

That one doesn't look too bad.  The outside looks like one of those ones you can detach. The coin isn't fused in, it's just clipped into the housing.

The solder wouldn't melt. Ended going at it with pliers and a file. I'm happier with it I suppose...
