White/Copper Spots Experiment

A 2005 a 1989 and Heyimderricks 2003 have been mailed today ,after cleaning to NGC ,let,s confirm how little I know about grading a coin ,I say the 1989 is a ms69, the 2005 is a ms68 ,and I have more faith in Derrick,s 2003 than he does:),I will call it an ms68.............

Wow, you really are the optimistic one! We make a good team at least. This will be fun.

Would be interested to see this on gold coins - often see gold coins from the 90s that have weird toning like they have been removed from their capsules and stored in an album etc.

Just tried this stuff on a gold coin that had some mild pvc residue. It did remove it after two cycles through the solution, rinse, and with some very light rubbing with my bare finger under water.

I think this is a mistake, rubbing will scratch and degrade the coin.

It could if done aggressively and with pressure. But I emphasize the very light, and bare finger again. Clean, wet skin isn't something I would consider abrasive. To each his own. I sent the coin off to NGC the other day as I was happy with the result. NGC graders handle your coins barehanded as well.

The PVC coin mentioned is coming back from NGC MS69.

JC also has some exciting results to share from our experiment. :D

This coin is coming back from NGC in MS68! Far better than I imagined. HQ photos to come once it arrives home.

It's also for sale for whoever wants it :cool:
 
some folks might not know ,but the cert # is your invoice # then dash and the 3 digit line item # on your Ngc invoice so you can actually view your coins before you receive them from NGC ,while waiting for them to get thru the mail
 
A total of three coins so far have been graded by NGC ,no problem after being dipped in the EZ-est coin cleaner ,I have played with the cleaner IMHO it does a great job in removing toning from silver coins.......... milk spots i think it can help on certain types ,as we all have seen on the 2003

I concur. This stuff works really well on surface contamination, including PVC. If done carefully and thoroughly, you can get great results and avoid damage to the coin. White spots and copper spots that are from substances in the metal itself cannot be removed with this stuff, but that shouldn't be a surprise. While it seems to be a proven, useful solution, it's important to keep expectations in check.

Alternative to NCS for the minor surface stuff? To me, yes. Alternative for major problems on high-value coins? Probably not.

Fun experiment. Many thanks to JC for his assistance and participation. :cool:

Just curious, how did your 89 and 05 grade?

I did a search and found some discussions about this product, as you can see from the 2nd thread below it's quite a controversial topic:

http://www.cointalk.com/t30122/
http://www.coincommunity.com/forum/topic.asp?TOPIC_ID=125536

And also a video showing it in use (fast forward to 3:25 to see the action):

As you can see, this stuff works fast.

LOL, of course it is controversial, especially when you find a board with old school coin collectors. The truth is, anything that has to do with "cleaning" a collectible coin is controversial to somebody in the coin world. It is inevitable. I've read threads about NCS where numismatists consider their techniques controversial as well. The simple fact is, NCS uses something to clean your coins. Purified, distilled water rinses alone aren't going to remove grit and grim and PVC and shine the surface of your coin. NCS may not disclose what they are doing or using in their processes, but it's cleaning under the term "professional conservation". They do amazing work, and I have paid handsomely for their services, but their process of neutralizing the surface of a coin is technically cleaning. I know this is going to get some people fired up. :rolleyes:

It's very easy to get into heated debates with collectors about this stuff. If you want to get into the grey area, obviously you can take cleaning to extremes where the coin is aggressively dipped and scrubbed. This to me is foolish and wrong, especially if you try to pass off a damaged coin to an unsuspecting buyer.

For me, with the 2003, I followed the directions on the solution, handled the coin with the utmost care and you can see the results for yourself. Obviously the coin shows no signs of improper treatment, surface damage, contamination or residues because it was graded by the experts and not sent home in a body bag. I take the experiment and results as a sign that we did this process in a responsible manner.

I think it was a good learning experience for all of us overall. :cool:
