Just interested it what you guys do with your old crappy coins that have gone green or are damaged in some way.
I store mine in an old KOTCT mug. Not sure what I'll do with them when that is full. Might be a while yet though.

The coins...
Forum won't allow me to post a picture of the coins.
All I get is this message...

Made the file smaller, so let's try gain.
(not that it was huge to start with)

That's the same message I get got when trying to upload the photo of the coloured canandian $2 coin. >:(
My cruddy coins are released into the wild again...

Many of those in the mug, aren't from Aus, so I can't release them. Some I could. :)
-
I try not to get too many of them. Some I end up getting anyway. If it's not a particularly scarce coin, I might use them for coin cleaning experiments. I have an EDTA-based formula that I've been experimenting with, with some success.
Coins that seem to "clean up OK" I keep, to watch for long-term adverse affects of the cleaning.
-
I try cleaning experiments as well or released back to the wild. I hope the green death doesn't contaminate your mug Steve, maybe put either a plastic cup or bag in to protect it or do you think the mug would be safe.

I don't use it for drinking out of. It's just for show. I think it will be OK. :)

If you find the perfect product to clean verdigris off of copper coins, let me know please. :)

I have seen that product before, but I've always wondered whether it would be allowed to shipped through the post.
Might have to give it a go and see.

Maybe you could get one for me as well to save on postage.

If I go ahead with that, I will get an extra one for you.
Might be couple of weeks before I do though.

I don't know what Badthad puts in to make Verdi-Care; it's a proprietary formula, so I doubt he'd tell you if you asked. But the material safety data sheet (http://www.wizardcoinsupply.com/old/files/images/Verdi-Care-SDS.pdf) from Wizard Coin Supply says it's non-hazardous and non-dangerous for shipping, so you should be able to ship it via any means that you could use to ship water.
He also claims it's non-corrosive; the MSDS says the pH is 7.5, so that seems a fair statement. It must contain a chelating agent that is also non-toxic; if I had to guess, I'd say it's triethanolamine-based, or something chemically related. Which would also make sense in that he was originally trying to invent a surface protectant; he serendipitously found that it removed verdigris too.

Just keep an eye on ya mug as it's a KOTCT so I'd hate to see it get destroyed :(
Try a wd type spray Steve as I find that works well ;)
Acetone on PVC and glue type substances.
They say olive oil is good for verdigris but you have to let it soak for months on end and I haven't had the patience to try that one (yes me not having patience is pretty funny so who would have guessed that LOL) so I tried quick fixes and found WD-40 or CRC does the job, just make sure you give them a good rinse in hot soapy water and dry well. Remembering all the time not to wipe the coin just pat it and any harder bits use a tooth pick.
BUT only do this for the preservation of coins not to make them pretty to sell. Yes I know your like me and prefer to give coin away but just saying :D
-
I do have bottle of acetone and that does work well on PVC and sticky stuff.
I have tried olive oil, with very little success, even after soaking for a year.
WD40 was better, but still not perfect. I have key date Lincoln cent that
really should be treated and I wanted to use a good product on it. I think
the Verdi-Care might be the way to go.
You're right mate, I prefer to trade or give them away. Not into selling coins.
Talking about that, keep an eye on the mail box in the next few days. :)

Very interested to see what you think about a verdi care or the like.
Cool, will let you know when it turns up :D
