Need Help

p.gee · August 30, 2017, 02:36:30 PM

Hoping to pick the brains of some of our experts. I have a heap of florins that I have removed from a Dansco push in album. These florins are mostly uncirculated with full luster on the reverse but the obverse has reacted with the album and turned a dull almost brown colour. Is there anything that I can do to improve the look without destroying any value that may be left.
Thanks P.Gee

Images of the affected coins would help.

Sorry, forgot the pictures.
This is one of the more expensive coins that I would like to save. Thankfully they don't owe me anything as they came in one of the collections that I bought a while ago, that has more than paid for itself all ready. So its all a bonus from here.
Thanks again for any help.

There's really not much you can do. Anything mechanical or chemical will alter the surfaces and destroy any remaining value. The best you can hope for is to neutralise/flush away any contaminants and prevent further deterioration.

Water, Acetone, RP7, ... anything gentle enough not to wreck the coin is going to be too gentle to address the problem.

One of those cases where prevention is the only answer. You should see the former pristine 50¢ collection I put into PVC pages when I first started, and forgot about until I found them a couple weeks ago. I actually felt bad throwing them in the pond, as they really weren't pleasant to touch.

A soak in Xylene will, maybe, be more effective than the agents Fulvio suggest. But probably not going to do much better (if at all).

If you send them to PCGS/NGC for "Conservation" they will Dip them and then grade them, However IF You dip them PCGS/NGC most likely Wont grade them and "Boddybag" them "Details altered surfaces".:angel:

The damage has already been done so all you can really do is use acetone/xylene to tidy them up a bit then put them in saflips/2x2's to arrest any further damage unfortunately.
BTW Nice 39 :good:

PCGS restoration for more expensive coins. I think the cost would be $200 or so...

USD 30 (about $40) or 2% is the minimum restoration and grading fee.

$20 grading fee (Economy)
$72.94 shipping (up to 10 coins
$30 Minimum for "restoration"
$30 registered postage to US

$152.94 USD or $192.33 AUD

Ausproofs $200 estimate is pretty spot on

Try warm soap and water.
Use soap that is more soluble and not perfumed.
Rinse in distilled water.

Also as Echidna said, warm soap and water works (I have only done this for cheap coins, if you have $$$$ I would go with restoration as you get a cleaner coin that is graded as well).

Unfortunately no amount of soap and water or acetone/xylene will remove the toning on these coins.
The coins have reacted with the cardboard in the push in albums which is Not uncommon with these types of albums.
I got rid of my Dansco push in albums a while back for this very reason.

Many coins are salvageable like the one I restored below but you have to review each
coin on a case by case basis and up the anti in stages as required but unfortunately
some coins are too far gone

Nice job there stevo

Is that just the warm soapy water method you used. I have a few that I wouldn't mind having a go at

Warm soapy water won't get that stuff off and neither will acetone so I use WD40
most of the time and it doesnt harm the surfaces so long as you dont let it soak
for too long,No more than 30 minutes at a time because if you leave it in the WD40
for more than that it will start to eat into the pattina.Mine will then generally grade at
PCGS no problem unless there are other issues.
BTW a lot of people will call this cleaning but at the end of the day I'd rather protect my
coins instead of leaving them to rot and anyway PCGS call it restoration
