Cleaning residue

Recommended Posts

Robdon

Evening

 

I recently bought a few coins, there seems to be a sticky residue on the coins, what is the best way to clean this sticky residue off.

 

Kind Regards

Acetone should take it of - I know it does wonders with copper/bronze coins but are not sure about silver coins.

 

After the acetone clears, the coin should have a whitish dull hazy appearance and then just dip it in gun oil (yes gun oil)

 

I use Ballistol-Klever Neo-Ballistol wonder army oil

 

I sold a SA Penny last year for R52 000 (NGC-graded) on BidorBuy that received this treatment.

 

If NCS can do it - it should not be that difficult.
