Don't you just hate...

Ordered some tonight from the chemist.
you're more than welcome to join me at auctions / viewing. Depending in the catalog ill probably be at the next roxburys too

careful with that stuff from the chemist
I have a large bottle of it
used it once ..... stinks to high heaven!!
now the bottle just sits on the shelf ... unloved!

ps I wonder if the stuff from the chemist might be stronger maybe than the bunnings stuff?

Doesn't matter where you buy it they are all the same (except chemist version may be very slightly purer).
Big W does have it as do most hardware stores.
I buy 1 litre bottle for around $10 to $12, as Nancy says. You can get 5 litre cans but a litre lasts months and months just for soaking coins. Do the soak in a sealed container to stop evaporation -acetone is very volatile. You can reuse it many times and, if it picks up some sediment just let it settle for a day and carefully pour the clean stuff off and toss the dregs.

WARNING[/size]Be very vary of reusing acetone too much if you are removing PVC goop off coins. Acetone will remove it from one coin but it can deposit some of it on another. For all my half decent coins I only use fresh acetone to soak and I even have a second bowl of fresh acetone to dunk the coins after they come out of the soak. Once I feel the acetone is PVC contaminated I only use it for the initial soak of batches of low grades that have lots of contamination to start with.

See so many handy hints here :good: so just small amounts at a time and dispose of it unless the next coin is very rough and it's just for a rough clean.
so is it easy to tell when it's contaminated, does it go cloudy, just want to know in case I ever do it, cheers.

Very easy on the Decimal "Silvers".
A light Blue/Green haze on the coin.
Treating with acetone does not guarantee a long term
preventative measure, the damage to the coin surface
may well allready have occured.

After Acetone Treatment
Eureka, so I thought :yahoo:

The Coin To-Day
Bummer the damage to surface had already occured :dodgy:
Reverse is damaged beyond repair.
May 2014

bummer, so the lesson here is if you clean them get rid of them pretty quickly afterward unless you really like the coins and can live with the look.
nice pic's BTW FP :good:

I'm hoping that it's possibly ink, and an acetone bath lifts it.

No luck with the acetone. Happy for other suggestions.
Too bad though, the strong die polish lines on the reverse look outstanding.

I've put this into my dansco. Nothing wrong with another one (up to 5 aunc / unc ones including 2 x slabbed ones)

[ausjack]

NOOOOOOOOO and it's so nice and no no suggestions sorry Rob

[robbiegal]

where is the PVC damage on this 1971 fifty cent?
is it in and around the 50   ?

Follow the The Red Arrows
That stuf is rough crusty black carbonised metal.
The rest of the coin is "As Struck"

[robbiegal]

bummer
the coin looks smashing

and thank-you Fordie

[ausjack]

yes it's a real shame as it's nice except for that..note to self, really look at older coins in PVC sets
