Hey, i don't know why but the inside of my coin unique is pretty rusty,

Rest of message deleted by Mods. The picture and comments were exposure and we just don't do that on TM. Please be more careful in future posts, thanks.

AS long as it works then I wouldn;t touch it.

You can clean the penny part with some tomato ketchup on an old tea towel but rub gently.

I agree, I wouldnt chance ruining the magnet personally. If it stopped working however then it would be a different story.

You could try a very light grade of sand paper, this would knock of some of the pretruding bits of rust. Either that or the wire brush attachment on a dremel multi tool just ensure you use it on a low speed!

This is a common thing with these sets, not because they get wet but just because of the natural moisture in the air getting trapped between the coins when the set is nested.

One thing that is worth remembering however is that rust is a great quietner. My hopping half set has been rusty on the inside for years, this stops the metal scraping against the metal and making that gawd awful tell tale noise as a Sh*** nests with its In****.

Personally however as I said already I would leave it until it gets so bad that it doesn't work.... which I doubt will ever happen. It doesnt really look THAT bad mate!!!!

As for the penny, just drop it in a can of coca-cola for an hour!!!! Or use a bit of brasso wadding. Just be careful that you don't make it too clean that it is no longer convincing!!!! People believe coins when they look dirty and used!!!!

Scotty

are you serious? using tomato ketchup?

[Off Subject ]And can i ask is it worth buying 'coin matrix' of eBay. I just saw a used one for £4. Or could you reccomend any tricks i should get?

Totally serious. Put an old 2p in some ketchup for an hour or so and just watch the dirt come off. It will look nearly as good as new.

It's all to do with the acid that's in the ketchup!

Delude,

Rust, once started, always gets worse unless stopped. I suspect the moisture has come from your hands. I would remove it with some fine wire wool from your local craft shop, and then make sure you dry the coins out when you finish performing using a tissue or kitchen towel.

You can clean up coins using vinegar by soaking for a while or Brasso which is also excellent for brass effects like Okito Boxes

So differnt people are sayin differnt things, should i use a wire brush or just leave it

Well I tried that and after half an hour Mcdonalds asked me to leave.

Apparently I was making a mess of the tables.

Lmao.

Typical of McD's

I wouldn't bother with cleaning the visible parts of the coins, unless they are really filthy. Ketchup/vinegar will clean copper coins, but it will just make it stand out as a shiny coin, and you don't see too many of them in circulation - bear in mind that you'll need to be able to match it or swap it with a borrowed/duplicate penny in some routines, and you're most likely to come across brown pennies.

Due to a moment of creative stupidity a while ago, I ended up having to remove superglue from my coin unique, and acetone nail polish remover seemed to do the job (eventually).

On gibson coins, there's a note on the instructions saying to wipe clean the coins after use, as the steel part inside corrodes quickly with sweat from hands. I think the only way to remove the rust is by carefully using friction, ie dremel/wet & dry/wire wool, but you'd have to be *very* careful not to damage the coin or shim.

It could be worth trying a small layer of sellotape over the internal shim to see if it stops corrosion. It fits in mine without fouling anything, and seems to make the attractive quality of the coin easier to control (for me) - but I don't know yet if it will help the corrosion much.

The slight added internal friction seems to stop the insert from spinning also, so it could be a good thing

I just tried the tape but it made it spin even more

Hmm, probably depends on the type/brand of tape. At least it's easy to try and then remove.

Hmm, thanks anyway
