Cleaned coins vs Uncleaned coins

cpm9ball, I like the after picture better my self. as for cleaning or restoring coins it is considered a no for most collectors, but I have had very good luck at touching up coins not really cleaning but removing surface grud + grime with hawthorn spikes and lightly soaking in water, not rubbing or scratching the surface then rolling a Q-tip over the surface with olive oil then dabbed with cotton cloth. I have sent my altered coins as some might call them to ICCS, CCCS, and PCGS and have never got a detailed coin or cleaned coin from any of them that I have cleaned or altered always a grade. So I'm guessing its all in how you attempt to clean or alter coins.

I am of the belief that all circulated coins have been cleaned at one point or another.

 

Soap and water. I understand the need for distilled water. What type of soap? I would think dish detergent is way too strong. What concentration?

 

For my eyes the second looks better.

 

Doug has sung this song many years, but I still think that the "residue" can be rinsed off.

 

Agree, however linseed oil is what is known as a "drying" oil and will react with air to form a protective plastic (if that's what you want).

 

Linseed oil on coins......interesting. Is it being done by collectors ? Are there different kinds of linseed oil, like boiled linseed oil.

 

Perfect way to put it IMO

 

That wouldn't be cleaning. If you can get some Methylene chloride or Chloroform, you can wet a Q-tip with the solvent and roll it over the surface. It will take the fog, which is probably PVC, right off without damaging the coins. This is not considered cleaning, it is preservation.

 

A simple dip in MS70 or just sodium hydroxide alone will take the haze off a proof coin too - easier to come by, and no need to roll a Q-tip around on the surface.

Edited: oops, he said cents. These treatments are controversial on copper.

 

Lindseed oil is something used by copper collectors may, many years ago to prevent Verdi grid and other things that can start in high humidity areas.

 

My thought was that I saw many collectors talking about using Museum Wax and In thought the linseed oil (or Stand oil) might be a better choice for penetrating cracks and crevaces.

 

I LOVE THE SMELL OF CHLOROFORM...BE CAREFUL, IT DON'T TAKE MUCH TO PUT YOU OUT!!!

 

It comes in handy being an analytical chemist. I haven't used carbon yet - it doesn't get used much anymore, but I would bet it would remove PVC better than the other two.

 

Every coin shown is cleaned. I'll take my bent pipes any day. One day, USA coinage will be in the same regard as these.

 

I noticed that bent pipes on Ebay sell very well
