to the CCF This won't end well. The millions of collectors that came before you say don't try to clean any coins with anything other than acetone and water, believe them.

Fair question but what makes you think you need to clean a coin?

It can be done successfully with the correct toolbox, patience, and a whole bunch of experience. But only advisable if there is literally no choice in the matter. I would never, ever consider any form of abrasive medium (e.g. rubbing required) or acidic agent.

As others have mentioned, Acetone & Xylene - VerdiCare for more advanced needs. IMO, the only tools worth mention.

Case in point - this needed to be done.

in general 'cleaning is a no no. there are some 'conservation' methods that can be used to restore a coin, but you must know what you are doing or you can ruin a coins value.

I conserved that SLQ.

But, as far as PCGS cost for conservation services, I think it is 3% of their posted value for a denomination/year/attribution. Really not well defined IMO, like no language if grading process details a coin that the conservation group completed, etc...

Dearborn, thread on it from past summer.

DW, Acetone, Alkali, VC (spot only). Time for each is coin/crud specific, nothing set in stone.

That's an excellent Conservation on that Standing Liberty.

Just curious, did it grade as "Cleaned"...
i would say no sign of cleaning from pictures.
