Hi There. I am a newbie here and have some stupid questions, so bear with me! :)
Can you still get coin rolls from the banks?
Can you clean proof coins? I have a 1970 proof set which has black spots on the coins. I will post pics when i get a chance.
I have started collecting silver lunar coins in the 1oz variety from Perth Mint (mainly to collect and eventually leave for my son). Mainly Series II in proof. I may also start collecting 1oz silver Bullion Lunar coins as i signed up with the perth mint, but will have to wait for the 2016 release as 2015 is all gone!
Found some 1942 & 1948 pennies whilst cleaning out the carport the other day. Will post pics so your learned selves can help me grade them. Thanks

Looking forward to some pic's and never a stupid question mate so go hard :good:
Now you can still get rolls but not very often they are RAM roll and done by the security companies so they aren't always the same coin so they're mixed rolls :dodgy:
Umm, no, we don't clean coins as such, unless you have nothing to loose but general rule is leave them. If you have sticky stuff on the coin you can try acetone, or WD40 or olive oil for the green death (verdigris) but be very careful and use cotton tips but very very gentle and watch the acetone doesn't eat the plastic on cotton tips and give a good rinse..but I didn't say any of that :angel:

QuoteCan you still get coin rolls from the banks?
Depends where you are, and what you're after.
There are three types of rolls now.
• RAM rolls, which may be in special paper or blank, released through dealers, only for some issues (last was 2014 green $2 in plain wrappers).
• ARMAGUARD rolls, which are delivered to branches with coin dispensing machines, and contain recirculated coins (although new coins are sometimes rolled in Brisbane).
• PROSEGUO (formerly CHUBB) rolls in green paper, which are delivered to ANZ and Bendigo Bank, which sometimes contain new coins (last I have is 2013 Coronation purple $2).
QuoteCan you clean proof coins?
Its a very bad idea to clean ANY coins, and especially proofs.
There are two ways you can clean coins. Chemically and Mechanically. Both leave evidence, and people won't buy coins which have been tampered with. Mechanical means will leave tiny scratches, which can be seen under magnification, and chemical means will remove metal, which will affect the lustre and make a coin look 'wrong'.
That said, if a coin is badly affected, it may be preferable to halt the damage, but you can't reverse or repair it. Seek expert advice, and be very, very gentle in anything you do. Distilled water is safe. Tap water not so much. Acetone is generally safe, as is RP7/WD40. Olive oil is mostly safe on single coins in glass containers. Lemon juice or Vinegar are the weakest acids, and may be useful in small doses. Anything stronger avoid like the plague, and never use abrasives, like Brasso, toothpaste, silver polish, etc. If you do want to try cleaning, start with some rubbish coins, document what you do and the results, and always finish with distilled water to remove all traces of whatever you used. Oh, and get yourself a USB microscope so you can really see what you're doing.

While PM do produce some lovely 'shinies', be aware that to a lot of people, these are just baubles, often referred to as NCLT or 'granny bait'. They are unlikely to hold any long-term value, beyond the precious metal content. By all means buy them if you like them (we all have some of these skeletons in our closets), but don't kid yourself that they're any sort of investment. If you are using them as such, stick to the Bullion coins, which don't carry anywhere near the premium pricing of the Collector coins. Also beware of NCLT from the RAM and private 'mints' like Macquarie.

We'd love to see them, but don't expect accurate grading from photos. If you tell us where you are, we can direct you to people you can talk to.

I will take pics and get some opinions

lol..I realise they are overpriced....but they are sooo shiny! I like the look and can afford the $100/year to collect them and they are not something I am looking to sell later on. Will also start collecting the bullion coins too.

Just after an guesstimate to satisfy my own curiosity...doubt they are worth anything... Thanks

That they are. Which is why we've all got some, even if we don't always admit to it. ;)
Hi qman69, :welcome: to The Australian Coin Forum. Great to see you posting! :yahoo:
Here is a scan of the spost/tarnish on the Proof Set...Not as clear as i would like. Might get a cheap USB Microsocope.. Copper coins seem ok, just the others are all tarnished to some degree. Still not worth an attempt at a clean? Thanks

The 1970 proof sets can be problematic as a lot of them were not sealed perfectly, That is why it is "tough" to get the 50 cent coin in grades higher than PR68 :ok:
I had to look at quite a few sets to find this one :)

nope don't clean them, it would only make them worse, actually de-value them more
:welcome: to ACF
Please do not clean them it de values them like anything
The only thing you can do is prevent further damage. Clearly the case isn't properly sealed, so seal it. I'm not saying reweld it, and I'm certainly not suggesting glues, which would likely cause more harm. But put it in a sealed container with both Oxygen and Water adsorbers, and you should stop the reaction. A clear Polypropylene (PP) or Mylar (BoPET) bag, or failing that even a (washed and thoroughly dried) chip packet will do nicely. But don't use Polyethylene, as it will let gasses through.
Trout, amazing 50 cent piece!
It's fine to say "don't clean it" when the coin is just a circulated and all that history and stains are part of its life but if there is a problem like mold, corrosion or PVC damage which is likely to make the coin worse over time, isn't it better to clean it carefully than just leave to deteriorate? The value has already been hammered down anyway. I am thinking of preservation what is left.

Yes
yeah but when someone says clean, i just imagine someone rubbing it, or putting fingerprint and wot nots on it, if you knew how to clean or improve it without actually rubbing it, then i don't see a prob, does acetone affect a proof frosting ?

That one is over at PCGS at the moment , it should come back PR69 hopefully :)
Quotedoes acetone affect a proof frosting ?
No.

Good advice
Good advice here, now that's funny :laugh2: more like lies lies and then some more lies just to be sure :angel:
Hello,
Has anyone tried an Ultrasonic cleaner ? It should loosen mould and stains as opposed to marks left by a chemical reaction.
QuoteHas anyone tried an Ultrasonic cleaner?
Yes. My comments can be found here...RE: Tarnished coin cleaning (http://www.australian-coins.net/showthread.php?tid=3835&page=6&highlight=cleaning)
I placed a glass jar in a cheap plastic "ultrasonic" cleaner, stuck it down with blue tack. Then some chamois in the bottom to create a soft non abrasive bed for the coins topped with about 2cm of acetone. That speeds up the cleaning from 5 hours to 15 minutes for the same result. The cheap cleaner does not really oscillate at ultrasonic speeds but keeps the liquid in motion to enhance cleaning action. The acetone gets dirty so it has to remove something from the coins, mainly PVC.
hmm...i might crack open the 1970 proof set and try acetone on it.. whats the worse that can happen? :dodgy:
